AB  - A modification of analytical procedure for energy-dispersive X-ray fluorescence (EDXRF) quantification of ten chemical elements (As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, Zn) in the leachates obtained from cement binders was developed. Twenty-nine testing samples were used in the experiment. All samples were based on Portland cement. Fly ash of different origin, zeolite and bentonite were employed as mineral additives in the cement binders. Distilled water was used as leachate. Validation of the modified EDXRF procedure was conducted in terms of limits of detection and quantification, working range, linearity, selectivity, precision, trueness, and robustness. Traceability of the procedure was established using certified reference materials. Uncertainty of measurement was confirmed via "in-house" laboratory validation approach. The expanded uncertainties for ten analysed elements were obtained for entire working range of EDXRF method. Robustness of the modified EDXRF procedure was assessed by means of chemometric in-house approach. The results obtained by modified X-ray fluorescence method were additionally correlated to those acquired by inductively coupled plasma optical emission spectrometry to confirm that EDXRF can be used as an effective and reliable alternative method for analysis of cement leachates.

AB  - Adjustment and subsequent validation of energy-dispersive X-ray fluorescence (ED-XRF) method for cement based binders with addition of mineral raw materials (fly ash, zeolite and bentonite) was conducted. Eighteen chemical elements present in the material composition were analyzed: ten major elements (Si, Al, Fe, Ca, Mg, S, Na, K, Ti, P) and eight trace elements (Cr, Zn, Cu, As, Ni, Pb, Sr, Mn). Thirty-five samples of either certified reference materials or reference materials of cement, fly ash and clay were utilized during adjustment and optimization of the investigated ED-XRF procedure. The method was consecutively validated in terms of selectivity, precision, working range, linearity, accuracy, robustness, limits of detection and quantification. Thirty-two samples in total, i.e. three certified reference materials and twenty-nine reference materials, were simultaneously analyzed by ED-XRF and inductively coupled plasma optical emission spectrometry (ICP-OES). Comparison of the outputs of monitored methods showed infinitesimally small differences, as correlation coefficients were extremely good (approximate to 1), which highlighted ED-XRF as highly satiable alternative for ICP-OES for the chemical analysis of cement binders.

AB  - New global tendencies for waste materials reusing in building materials are imposing the request for improved performances of chemical analysis methods and the improvements of matrices used. A new method for optical emission spectrometry with inductively coupled plasma (ICP-OES) is developed and validated for the chemical analysis (35 elements: Al, Be, Cd, So, Cr, Cu, Fe, Mn, Mo, Ni, V, Mo, Zn, Pb , Bi, Si, Zr, W, As, Se, Sb, Sn, Ti, Ba, B, Ag, Mg, Ca, K, Na, S, P, Ga, In, Li) in leachate of fly ash. Validation performances and the uncertainty of measurement were resolved. Uncertainty of measurements were resolved by three routes: validation procedure, participation in proficiency testing (PT) schemes and standard method. The obtained method is a new simple and effective analyzing route for determination of undesired trace elements and their quantity comprised in leachates of fly ash, and leachates of building materials with addition of fly ash (cement binders and mortars). In order to prove its accuracy and precision, the developed method was employed on laboratory samples of cement binders and mortars. Results were compared with limit values provided in the standard. Multivariate analyses, i.e. cluster analysis and principal component analysis, were applied to establish interrelations between analyzed samples, and to certify the developed ICP-OES method.

AB  - In this study, new refractory coatings based on synthesized cordierite for the casting applications were developed. The investigation included starting raw materials characterization, synthesis of the cordierite, design of the refractory coating as final product, and its application testing. The obtained results pointed out that coating suspension sediment stability was crucial quality parameter. Design and optimization of the coatings composition, with controlled rheological properties included, were achieved by application of different coating components, namely different suspension agents and by alteration of the coating production procedure. Cordierite, used as filler, was obtained by means of synthesis in the solid-state reaction on the basis of talc, kaolin, and alumina. The investigation showed that the application of these particular types of water/alcohol-based coatings has positive influence on surface quality and structural and mechanical properties of the castings of aluminum alloys obtained by casting into sand molds by means of evaporable models method, that is, evaporate pattern casting process.

AB  - Various possibilities for developing new mullite-based refractory linings that can be applied in a casting process were investigated and are presented in this paper. An optimization of the refractory-lining composition design with the controlled rheological properties was achieved by applying different lining components and altering the lining-production procedure. Mullite was used as a high-temperature filler. A mullite sample was tested with the following methods: X-ray diffraction analysis, differential thermal analysis and scanning-electron microscopy. The particle shape and particle size were analyzed with the program package for an image analysis called OZARIA 2.5. It was proved that an application of this type of lining has a positive effect on the surface quality, structural and mechanical properties of the castings of Fe-C alloys obtained by casting into sand molds, according to the method of expandable patterns (the EPC casting process).

AB  - The aim of this study was to investigate the influence of various process parameters on the microstructure of composite materials based on alloys All 8Wt%Si with the addition of 10Wt%SiC. The effect of stirring speed (1000 and 1500 rpm), stirring time 15 min and casting temperature 565 degrees C on the structural and mechanical properties are discussed. It was found that applying the stirring speed of 1500 rpm in semisolid state the best distribution of SiC particles in the matrix was achieved, which gave satisfying mechanical properties. In order to evaluate the quality of obtained composites and their possible application in the practice, tests were carried out under conditions of cavitation. Cavitation damage to the composite samples was determined using modified vibratory cavitation equipment. Mass loss and surface analysis of composite samples during the experiment were used as an indicator the level of cavitation damage. The results showed very good cavitation resistance which gives the possibility of using these materials in condition where cavitation resistance is needed.

AB  - Methods for the investigation of microstructure of construction concretes are presented in this paper. Concrete is a composite material, thus its microstructure consists of bonding agent (cement) and aggregate with predefined grain sizes. Microstructure can be investigated with methods such are: scanning electron microscopy (SEM) and Image Pro Plus - PC program for image analysis. Phase content and certain properties can be investigated using X-ray diffraction, DTA, TGA and dilatometer. Metods are described using sample of concrete with recycled chamotte filler.

Mikrostrukturu betona, kao kompozitnog materijala, čine vezivo i zrna agregata definisanih veličina i za ispitivanja se mogu primeniti: mikroskopija (SEM i optički mikroskop) i metoda kompjuterske analize slike - Image Pro Plus. Fazni sastav betona i pojedina svojstva mogu se odrediti pomoću X-ray difrakcije (rendgena), diferencijalno termijske analize - DTA, termogravimetrijske analize - TGA i dilatometrijske metode. Prikaz metoda izvršen je na uzorcima betona sa punilom na bazi recikliranih šamotnih opeka.",

AB  - In this paper temperature difference and resistance parameters were used for prediction of thermal shock behavior of alumina based commercial refractories with content of Al2O3 from 28 % to 78 %. Thermal and mechanical properties of the materials were measured. Thermal shock stability was measured using water quench test (JUS. B. D.8. 319.) as experimental method. Values of temperature difference were calculated using heat transfer conditions and material properties. Equation given by J.H.Ainsworth and R.H.Herron for temperature difference was used. The heat transfer coefficient under conditions of free convection for a circular cylinder held in stationary position was calculated for water bath from equation given by Holman. Quenching heat transfer coefficient was also calculated, using expressions given by Sparrow and Cess. Calculated values of temperature difference were compared to measured number of quench experiments. Linear regression analysis was used to determine the correlation between calculated values for critical temperature difference with the results of water quench test. Resistance parameter was used for describing the thermal stability of the samples. Resistance parameter was calculated using usual equation based on material properties. Ultrasonic measurements for ultrasonic velocity, strength degradation were used for describing the resistance parameter degradation. Resistance parameters degradation was related to the number of quench experiments.
