AB  - The pattern recognition approach, explored by this study, applies the principal component analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation and propagation of the cracks and defects that appear on the surface of material exposed to the cavitation. The experiment was performed in four stages: (a) synthesis of two ceramic materials (cordierite and zircon); (b) subjecting the samples to the cavitation; (c) using image analysis software for collecting the data about morphological characteristics that describe defects; (d) principal component analysis as a pattern recognition tool in order to characterize the defects at the material surface. Besides that, according to standard, cavitation erosion was monitored by determining material mass loss during the cavitation. Large experimental datasets collected from morphological descriptors by image analysis are multivariate and difficult to interpret, thus are processed by principal component analysis as the most informative technique for extracting possible differences. The performed approach proved that this method has a great potential for better assessment of induced defects by proper distinguishing among them at different levels and that can be considered a very efficient and cost-effective one.

AB  - Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected
when fluid flow is present, which contains equipment such as turbine blades, high-speed propellers, or
pump parts. Cavitation erosion usually causes surface degradation of material with defects that appear in
the form of pits and fractures. Such loss of material leads not only to surface degradation but usually also
to strength deterioration with the potential risk of failure and therefore also to shortening of material
lifetime, thus requiring additional costs for failure analysis, repair, and replacement of parts. This paper
will present the results regarding the resistance of various engineering materials to cavitation erosion. As
materials, austenitic stainless steel 316L and CuAlNi shape memory alloy are selected and studied. The
comparison of the behavior between these two materials in cavitation erosion conditions will be shown
based on the results of mass loss and morphology analysis of the pits formed at the surface over time. Image
analysis tools will be applied in order to quantify the surface damage level and to analyze selected
morphology descriptors.

AB  - The majority of refractories used today are associated with the iron and steel industries. Typically, the refractory lining of a blast furnace consists of a combination of different refractory materials chosen for different portions of the furnace, as well as distinct process conditions and temperature ranges. Knowledge and requirements for the iron manufacturing system in conjunction with the physical, mechanical, and chemical qualities of the proposed refractories determine the choice of refractory combination. Inadequate understanding of the aforementioned components frequently results in refractory failure, which then becomes a difficult problem to tackle. A blast furnace's refractory liner typically fails owing to any number or combination of these variables. To facilitate comprehension, we will explain the types of refractory lining required in a blast furnace by region, as well as the observed trend in refractory lining patterns over the past few decades.

Demands for high-temperature materials are becoming more and more challenging every year. To perform efficiently, effectively and at the same time to be economically viable, the materials used at high temperatures must have certain characteristics that are particularly expected for applying under such extreme conditions, for example, the strength and thermal resistance. In the present review, some important requirements that should be satisfied by high temperature materials will be discussed. Furthermore, the focus is put on refractory concretes, ceramics, intermetallic alloys, and composites as four different categories of these materials, which are also considered in respect to possibilities to overcome some of the current challenges.

AB  - Although a most prominent material in contemporary construction practice due to its’ obvious advantages, concrete incorporates a number of drawbacks. It is one of the most advantageous principles for decades to enable a large-scale on-site application of this materials with acceptable properties, needed to withstand specific conditions. A concept of 3d printing concrete presents a promising ground for further improvement of this principle. While maintaining as much as possible of the prerequisite and common properties to answer the construction demands, this material has to evolve as much as possible to fulfill the 3d concept, which would, in turn, pave a way for next level of its wide range of construction applications. This paper aims to contain main principles of 3d printing concrete, discussing the main goals and the drawbacks that have to be addressed and solved prior to wider application. Also, wind tower construction, as a specific construction will be discussed as a potentially promising ground for this old construction material dressed in a new suit.

AB  - Electric power in Serbia is predominantly provided by thermal power plants. All of eleven existing thermal power plants in Serbia use coal, mainly lignite in the electricity production process thus generating about 6 million tons of fly ash per year. The estimated amount of fly ash from thermal power plants accumulated in Serbian landfills exceeds 200 million tons. On the other hand, during the last decades, respecting the principles of ecologically sustainable development has been imposed on industries, and one of them is the construction industry. Due to the presence of amorphous SiO2 and Al2O3, fly ash as pozzolanic material is convenient for the production of concrete and mortar. Consequently, multiple positive effects can be expected by the proper consumption of fly ash- reducing landfills and improving concrete properties. The idea of this study is to analyze the possibility of recycling fly ash from a thermal power plant by replacing a part of common mineral filler- limestone in the production of self-compacting concrete (SCC). Properties of conventional SCC with limestone and compositions with different fly ash content were compared. Considering that requirements for SCC should be satisfied and all properties remain or enhance in the case of fly ash addition, this study proved that all designed concretes can be used for structural applications.
AB  - Električnu energiju u Srbiji pretežno obezbeđuju termoelektrane. Svih jedanaest termoelektrana u Srbiji koriste ugalj, uglavnom lignit u procesu proizvodnje električne energije, čime se godišnje generiše oko 6 miliona tona letećeg pepela. Procenjena količina letećeg pepela iz termoelektrana akumulirana na deponijama u Srbiji prelazi 200 miliona tona. S druge strane, poslednjih decenija poštovanje principa ekološki održivog razvoja nametnuto je industrijama, a jedna od njih je i građevinska. Zahvaljujući prisustvu amorfnog SiO2 i Al2O3, pepeo kao pucolanski materijal pogodan je za proizvodnju betona i maltera. Zbog toga se pravilnom upotrebom letećeg pepela mogu očekivati višestruki pozitivni efekti- smanjenje deponija i poboljšanje svojstava betona. Ideja ovog istraživanja je analiziranje mogućnosti recikliranja letećeg pepela iz termoelektrane tako što će delimično zameniti uobičajeni mineralni punioc- krečnjak u proizvodnji samozbijajućeg betona (SCC). Upoređena su svojstva konvencionalnog SCC sa krečnjakom i kompozicija sa različitim sadržajem pepela. S obzirom da je u slučaju dodatka letećeg pepela potrebno da budu zadovoljeni zahtevi za SCC, kao i da svojstva betona ostanu ista ili poboljšana, ova studija je pokazala da se sve dizajnirane smeše mogu koristiti za konstrukcijske primene.

AB  - Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore chemically inert and to compare the properties of produced concrete samples. Fresh concrete properties included: slump-flow, t(500), V-funnel time, L-box ratio, segregation ratio, density, and entrained air content. Hardened concrete was tested for compressive, flexural and bond strengths, ultrasonic velocity, dynamic elasticity modulus, dynamic Poisson's ratio, and microstructure. Flowability and segregation increased, while bulk density, compressive and flexural strength, dynamic elasticity modulus and ultrasonic velocity slight declined. Times t(500) and V-funnel time, L-box ratio and entrained air changed insignificantly. Considering that all properties should remain or improve in case of waste valorization and the criteria should set to satisfy requirements for SCC, this study proved that all mixtures can be used for structural applications.

AB  - The cold spray technique was employed in this study to produce pure nickel (Ni) and nickel-Inconel 718 powder deposits on duplex stainless steel substrates. High quality coatings were manufactured using nitrogen as the propellant gas. The coatings exhibited satisfactory Inconel 718 (In718) retention within the Ni matrix due to the highly ductile binder phase necessary for fabrication. The characterization of the coating microstructures was implemented by means of X-ray diffraction, electron microscopy, energy-dispersive X-ray spectroscopy, and microhardness testing. In addition, the erosion resistance of both coatings was evaluated by performing cavitation erosion tests, with the analysis of the eroded surfaces revealing different erosion mechanisms for each coating. The results demonstrated the efficiency of the cold spray technique for use in the production of metal-metal matrix composite coatings and the potential of In718 use in applications which demand enhanced cavitation erosion resistance.

AB  - This study analyzes the feasibility of valorizing industrial by-product, fly ash from a thermal power plant as a partial replacement of mineral filler-limestone for the production of self-compacting concrete (SCC). Three types of SCC mixtures with different portions of fly ash and the reference mixture with limestone were designed. The synthesized SCCs in the fresh state were examined for density, entrained air content, flowability (Slump flow, Slump flow time (t500), V-funnel time (tv)), passing ability (L-box), and segregation resistance, while hardened state testing included: density, compressive and flexural strength, static modulus of elasticity, water permeability, resistance against freezing in the presence of deicing salt, and SEM analysis. Taking into account the obtained results it can be concluded that the addition of fly ash has a positive impact on the concrete properties and that the optimal content of fly ash is 20 % with respect to the total filler mass.

AB  - Stabilization of heavy metals, especially copper, from acidic mine wastewater is performed by their solidification into sulfur polymer concrete as an environmentally acceptable building material. The procedure is carried out by heating the aggregate in an amount of 56 mass % in a reaction vessel with continuous mixing up to a temperature of 160 °C. Subsequently 5 mass % of fly ash from the thermal power plant is added as a filler and 6 mass % of fly ash pellets with absorbed heavy metals from mine waters. Finally, 33 mass % of the sulfur modified binder, that is mixed melted elemental and modified sulfur in the mass ratio of 98.2 % : 1.8 % is added to the homogenized solid mixture. Modified sulfur is prepared by mixing the elemental sulfur that is by-product of oil refining with dicyclopentadiene at a temperature of 132-141 °C. After the homogenization of the sulfur polymer concrete mixture for 2-5 minutes, the resulting melted mixture is poured into the molds pre-heated to 120 °C and vibrated for 10 seconds. Thus obtained surface of the sulfur polymer concrete mixture is flattened and leave to harden in the mold at room temperature. The samples were removed from the mold after 3 hours of hardening and then cured at room temperature for another 24 hours. After characterization, obtained building material showed satisfactory properties required for all application areas of conventional concrete. By this process, heavy metals from mine wastewater were eliminated, industrial by-products (fly ash and sulfur) were used thus reducing their landfills, while the obtained material does not lead to secondary environmental pollution and therefore is considered as environmentally friendly.
AB  - Stabilizacija teških metala, posebno bakra, iz kiselih otpadnih rudničkih voda izvodi se njihovom solidifikacijom u sumpor polimerni beton kao ekološki prihvatljiv građevinski materijal. Postupak se izvodi tako što se u reakcionom sudu agregat u količini od 56 mas. % zagreva na 160 °C. Zatim se dodaje 5 mas. % letećegpepela iz termoelektrane kao filera i 6 mas. % peleta letećeg pepela sa adsorbovanim teškim metalima iz rudničkih voda. Homogenizovanoj čvrstoj mešavini dodaje se 33 mas. % rastopa elementarnog i modifikovanog sumpora, tzv. sumpor modifikovanog veziva u masenom odnosu 98,2 % elementarnog sumpora i 1,8 % modifikovanog sumpora. Modifikovani sumpor dobijen je mešanjem elementarnog sumpora kao nus-proizvoda iz rafinacije nafte sa diciklopentadienom, na temperaturi od 132-141 °C. Nakon homogenizacije u trajanju od 2 do 5 minuta, dobijena mešavina izliva se u kalupe prethodno zagrejane na 120 °C i vibrira 10 sekundi. Površina ovako dobijene sumpor polimerne betonske mešavine se izravna i ostavi da očvrsne u kalupu na sobnoj temperaturi.

abstract = "Stabilization of heavy metals, especially copper, from acidic mine wastewater is performed by their solidification into sulfur polymer concrete as an environmentally acceptable building material. The procedure is carried out by heating the aggregate in an amount of 56 mass % in a reaction vessel with continuous mixing up to a temperature of 160 °C. Subsequently 5 mass % of fly ash from the thermal power plant is added as a filler and 6 mass % of fly ash pellets with absorbed heavy metals from mine waters. Finally, 33 mass % of the sulfur modified binder, that is mixed melted elemental and modified sulfur in the mass ratio of 98.2 % : 1.8 % is added to the homogenized solid mixture. Modified sulfur is prepared by mixing the elemental sulfur that is by-product of oil refining with dicyclopentadiene at a temperature of 132-141 °C. After the homogenization of the sulfur polymer concrete mixture for 2-5 minutes, the resulting melted mixture is poured into the molds pre-heated to 120 °C and vibrated for 10 seconds. Thus obtained surface of the sulfur polymer concrete mixture is flattened and leave to harden in the mold at room temperature. The samples were removed from the mold after 3 hours of hardening and then cured at room temperature for another 24 hours. After characterization, obtained building material showed satisfactory properties required for all application areas of conventional concrete. By this process, heavy metals from mine wastewater were eliminated, industrial by-products (fly ash and sulfur) were used thus reducing their landfills, while the obtained material does not lead to secondary environmental pollution and therefore is considered as environmentally friendly., Stabilizacija teških metala, posebno bakra, iz kiselih otpadnih rudničkih voda izvodi se njihovom solidifikacijom u sumpor polimerni beton kao ekološki prihvatljiv građevinski materijal. Postupak se izvodi tako što se u reakcionom sudu agregat u količini od 56 mas. % zagreva na 160 °C. Zatim se dodaje 5 mas. % letećegpepela iz termoelektrane kao filera i 6 mas. % peleta letećeg pepela sa adsorbovanim teškim metalima iz rudničkih voda. Homogenizovanoj čvrstoj mešavini dodaje se 33 mas. % rastopa elementarnog i modifikovanog sumpora, tzv. sumpor modifikovanog veziva u masenom odnosu 98,2 % elementarnog sumpora i 1,8 % modifikovanog sumpora. Modifikovani sumpor dobijen je mešanjem elementarnog sumpora kao nus-proizvoda iz rafinacije nafte sa diciklopentadienom, na temperaturi od 132-141 °C. Nakon homogenizacije u trajanju od 2 do 5 minuta, dobijena mešavina izliva se u kalupe prethodno zagrejane na 120 °C i vibrira 10 sekundi. Površina ovako dobijene sumpor polimerne betonske mešavine se izravna i ostavi da očvrsne u kalupu na sobnoj temperaturi. Nakon 3 časa očvršćavanja uzorci se vade iz kalupa i neguju na sobnoj temperaturi tokom 24 časa. Dobijeni materijal je nakon ispitivanja pokazao zadovoljavajuće karakteristike potrebne za sve oblasti primene konvencionalnih betona.

AB  - In this study the resistance of cordierite and zircon to the cavitation erosion was investigated with the aim of possible spreading their application. Cavitation erosion test was applied using standard ultrasonic vibratory set up with stationary sample. Weight loss and image analysis measurements including morphological analysis of the formed pits were used for monitoring degradation during the cavitation erosion testing. The obtained results were discussed in order to compare and analyze degradation mechanism and the resistance of the investigated materials to cavitation erosion. Cordierite sample underwent less serious degradation, characterized by continual forming of new pits, while zircon degradation progressed by growth and merging of already formed pits.

AB  - Pulse-reverse power modes are used in galvanotechniques in order to obtain coatings with better characteristics in terms of gloss, adhesion, tracking sharp edges and uniform distribution of deposits on complex shape objects, compared with the coatings produced by constant current modes. Pulse-reverse modes also allow the use of a higher current density, and thus the production speed of electroplating cells increases. Systems for standard electroplating of copper, silver and gold are optimised by the suitable choice of duration and intensity of the pulses. It is shown that coatings with satisfactory quality can be deposited using higher current density, different modes of pulsed current in a very short period of time, without expensive and often dangerous additives in the electrolyte. Parameters of the model for certain electrochemical systems were determined by modelling and computer simulation, so the system behaviour under different circumstances becomes predictive.

AB  - Systematic modification of three structurally different minerals (zeolite, mica, and vermiculite) was carried out with the aim of determining the modification mechanism and exposing the hydrophobic surface that can be used as a sorbent for many organic compounds. Mechanism of modification with cationic surfactant depends strongly on the mineral type. In order to identify the influence of aluminosilicates structural differences on the modification process, adsorption experiments with organic matter and water vapor, supplemented with the DTA/TG analysis, were performed. The cation exchange capacity (CEC) value was 1454 gt 560 gt 28meqkg(-1) for zeolite (clinoptilolite), vermiculite, and mica (muscovite), respectively. Despite its CEC value, vermiculite adsorbed three times the amount of organic matter than did clinoptilolite due to the porous structure of zeolite, which acted to limit the adsorption only on the external exchangeable cations. If the loading amount is equal to the CEC or the external cation exchange capacity for clinoptilolite (ECEC approximate to 10% CEC), the monolayer will form while mineral surface will have hydrophobic character. Only one active center exists at the surface of the clinoptilolite that was identified by DTA curves with a sharp and defined peak around 300 degrees C and by the mass loss at the TG diagrams. Two significant and equal active centers were observed in vermiculite, one for the exchange of the surface cations and the other for the interlayer cations and H2O molecules. Muscovite CEC is negligible, and due to the absence of any other functional groups, the modification of this mineral was impossible.

AB  - In this paper the ability of three natural zeolites from different localities (Vranjska banja-VB, Igroš-I and Baia Mare-BM deposits) to remove copper has been investigated. These three zeolites were subjected to the elementary analysis as well as XRDP and DTA/TG analysis due to complete characterization. Cation exchange capacity of VB, I and BM zeolites were 150.1, 169.2, and 176.5 meq/100g. The maximum adsorption capacity for the copper adsorption on VB, I and BM-zeolites were 7.75, 8.51, and 11.18 mg/g. Based on the obtained results the mathematical expression that describes correlation between the CEC and copper adsorption capacity has been developed. This linear dependance has been tested with the vast variety of experimental results. According to this expression it is possible to predict the copper adsorption capacity for different zeolites based only on their CEC value.

AB  - The possibility of applying fly ash from power plants as a binder in supercapacitor electrodes based on activated carbon was investigated in this research. Based on the mechanical and electrical properties of the electrodes, the optimal ratio between fly ash and AC was determined. Supercapacitor electrodes were prepared in two ways: by pressing and by laser solidification. The preparation method significantly affected physical properties of the electrodes as well as the electrochemical behavior in supercapacitor setup. The electrodes were electrochemically tested by galvanostatic and potentiostatic methods and cyclic voltammetry. In order to improve the estimation of supercapacitor parameters, mathematical model that perfectly describes the behavior of investigated electrodes in aqueous solution of sodium nitrate was developed. The best results were obtained with laser-solidified electrode in 1M aqueous solution of NaNO3. Specific capacitance of 105 F/g, serial resistance of 0.57 Omega and self-discharge resistance of 95 Omega were achieved. Stability at high number of cycles proved to be very good. After 2000 cycles of CV at scan rate of 100 mV/s, specific capacitance fell by only 4.6 %.

AB  - Coating materials are widely used in refractory lining to prevent different deleterious effects such are reactions on the mold-metal contact surface, abrasion from liquid metal or alloy, gasses, slags, and other materials in contact with the coating. In this paper, behavior of cordierite based coating exposed to the cavitation erosion was investigated. Cordierite samples sintered at 1200 and 1400 degrees C were used for the tests. Mass loss, level of surface degradation obtained using image analysis and thermal imaging analysis were applied for the cavitation erosion evaluation. Results showed that the cordierite samples can be successfully used in conditions where the cavitation resistance is required.

AB  - Based on the nature of the matrix material, modern composites can be generally classified into three categories: polymer matrix composites, metal matrix composites, and ceramic matrix composites. Polymer matrix composites are not as strong or heat-resistant as metal matrix and ceramic matrix composites and therefore are restricted to secondary structures in which operating temperatures are lower than 300° C while for higher temperatures, metal matrix and ceramic matrix composites are required. Polymeric materials based on inorganic components can play an important role in various technological processes but their production on an industrial scale is still problematic. However, inorganic polymers, in combination with other materials can generate composite materials of very high quality and possibilities of applications. Among plenty of inorganic materials that can generate polymer chains, special attention should be paid to sulfur. One of the most popular applications of waste sulfur from the oil refining process is to produce a modified sulfur binder, which is predominantly implemented in different compositions of sulfur- polymer matrix composite materials used for diverse applications. Using sulfur as a binder is based on its physical and chemical characteristics: chemical passivity, excellent resistance to aggressive agents (mainly acids and salt solutions, but not bases) and hydrophobic properties. Sulfur implementation for composites production has started with using unmodified sulfur as a binder. However, despite excellent mechanical properties after preparation, samples exhibited low stability, so spalling and failure occurred after a short period. The development of modified sulfur binder contributed to better endurance of sulfur- polymer matrix composites, which focused its application for roads construction and repairing and as a building material. Sulfur itself tends to polymerize to a large extent while chemical modification increases this tendency or prolongs the time required for the polymerization. Except the prevention of sulfur transformation from monoclinic to orthorhombic form, the degree of sulfur polymerization is increased and long chains are created due to modification. Sulfur- polymer matrix composites are thermoplastic materials made of mineral aggregate and filler, with sulfur as a binder (instead of cement and water) at temperature above the hardening point of sulfur (120 °C). The proportion of aggregate, filler and binder for the preparation of sulfur- polymer matrix composite mixture may vary depending on the application. The choice of filler is important because it forms with sulfur paste that coats and binds the aggregate particles. In this chapter, various fillers were used for the production of sulfur- polymer matrix composite samples: talc, alumina, microsilica and fly ash. Durability of the obtained sulfur- polymer matrix composite samples was investigated under influence of acids (hydrochloric and sulfuric acids) and salt (sodium chloride) by monitoring their physico-mechanical characteristics. It was concluded that the used filler had influence on the behavior of the sulfur- polymer composite samples in the investigated environments.

AB  - Lifetime prediction for construction material is essential and very often crucial for determination of impact on material application and service. Many models based on different parameters were used to monitor materials behavior subjected to different extreme conditions such as thermal shock and erosive wear. In this chapter, image analysis for lifetime prediction of refractory concrete, more precisely low cement high alumina castable, during the thermal shock and cavitation erosion was studied and discussed. Generally, analyzed material has the properties that depend on sintering temperature but usually is a material with very high strength, density, hardness, and good thermal stability resistance. Usage of image analysis for lifetime prediction of refractory concrete during the thermal shock and cavitation erosion were the goals of this study. Thermal stability was investigated using most common experimental method, water quench test. Destruction of samples during the testing was monitored by image analysis. Results obtained from the image analysis of samples surface and bulk give proof that the level of degradation induced by extreme conditions can be monitored by this way. Values of degradation level were used for lifetime modeling expressed as strength degradation, and correlated to the experimental values. Based on the models for strength degradation using degradation level as variable, model for lifetime was proposed. Similar approach was applied in case of monitoring the degradation level caused by cavitation erosion experiments. The fluid dynamic system of the experimental methodology used to produce ultrasonic erosive wear. Mass loss and level of material degradation were measured before and during the experiment. Level of degradation, that is average erosion area were monitored by using Image Pro Plus program for image analysis. Obtained results showed that after 180 minutes sample exhibited excellent erosion resistance compared to metallic and ceramic samples. Level of surface degradation did not overcome 8 % compared to the original surface.

AB  - The degradation of concrete structures, which progresses as time passes, is caused by external factors such as chemical, physical and mechanical interferences. In the case of chemical deterioration, various ions penetrate from the surface and then permeate into the concrete. Concrete structures are more or less porous materials, which have pores with a range of diameters. These pores have a detrimental influence on the strength of concrete and on the durability because they become permeation paths for other deterioration factors. Degradation of concrete structures often results in initiation and propagation of micro-cracks and other micro-defects. Since the presence of micro-cracks can significantly influence the mechanical properties of concrete, detection and control of micro-cracks is an essential issue for its durability. The prediction of material macroscopic properties requires a method capable of quantifying the material microstructural characteristics. Image analysis of the sample surface destruction is an important non-destructive method for assessing damage of the materials. Due to image analysis, more systematic and more accurate measurements have become possible. Therefore, more objective characterization of concrete structures from the aspect of material properties is provided. Evaluation of various concrete properties, as well as the effect of external influences on the microstructure of concrete, can be investigated using these non-destructive methodologies. The objective of the current study is focused on the quantifying surface cracks in concrete structures by using image analysis technique. In this chapter, application of image analysis in monitoring the level of surface destruction of sulfur concrete and Portland cement concrete subjected to corrosion conditions was presented. Macro- scale image analysis was realized with taking into account the total surface of the samples in order to monitor damage distribution at the surface. Micro- scale image analysis was applied to the specific areas of the sample surface, detected by the macro- scale image analysis as potential critical areas for further deterioration. Based on the image analysis results, the model for prediction of mechanical strength degradation was given. Mechanical strength measuring of the concrete samples was realized using classical, destructive testing method according to the standard. Agreement between calculated and experimental mechanical strength values confirmed that the proposed model was acceptable. The quantitative nature of this data and its regular collection can promote the establishment of deterioration criteria through the determination of correlation between deterioration factors and damage within concrete structures. In this context, this study constitutes an important contribution to a better understanding of image analysis, and how such tools can be used to assist in the assessment of the condition of concrete structures in order to provide more reliable concrete monitoring.

abstract = "The degradation of concrete structures, which progresses as time passes, is caused by external factors such as chemical, physical and mechanical interferences. In the case of chemical deterioration, various ions penetrate from the surface and then permeate into the concrete. Concrete structures are more or less porous materials, which have pores with a range of diameters. These pores have a detrimental influence on the strength of concrete and on the durability because they become permeation paths for other deterioration factors. Degradation of concrete structures often results in initiation and propagation of micro-cracks and other micro-defects. Since the presence of micro-cracks can significantly influence the mechanical properties of concrete, detection and control of micro-cracks is an essential issue for its durability. The prediction of material macroscopic properties requires a method capable of quantifying the material microstructural characteristics. Image analysis of the sample surface destruction is an important non-destructive method for assessing damage of the materials. Due to image analysis, more systematic and more accurate measurements have become possible. Therefore, more objective characterization of concrete structures from the aspect of material properties is provided. Evaluation of various concrete properties, as well as the effect of external influences on the microstructure of concrete, can be investigated using these non-destructive methodologies. The objective of the current study is focused on the quantifying surface cracks in concrete structures by using image analysis technique. In this chapter, application of image analysis in monitoring the level of surface destruction of sulfur concrete and Portland cement concrete subjected to corrosion conditions was presented. Macro- scale image analysis was realized with taking into account the total surface of the samples in order to monitor damage distribution at the surface. Micro- scale image analysis was applied to the specific areas of the sample surface, detected by the macro- scale image analysis as potential critical areas for further deterioration. Based on the image analysis results, the model for prediction of mechanical strength degradation was given. Mechanical strength measuring of the concrete samples was realized using classical, destructive testing method according to the standard. Agreement between calculated and experimental mechanical strength values confirmed that the proposed model was acceptable. The quantitative nature of this data and its regular collection can promote the establishment of deterioration criteria through the determination of correlation between deterioration factors and damage within concrete structures. In this context, this study constitutes an important contribution to a better understanding of image analysis, and how such tools can be used to assist in the assessment of the condition of concrete structures in order to provide more reliable concrete monitoring.",
