AB  - The thermal stability, dynamic Young's modulus of elasticity, anisotropy and damage level of a 42% alumina refractory material were investigated using a water-quench test. Thermal quenching of refractories leads to crack nucleation and propagation, which result in loss of strength. Ultrasonic velocity and strength change in the sample in two directions was used to describe the anisotropy of the sample and its influence on the thermal shock resistance of the material. The study suggests that the results of the sonic measurements could be used for prediction of damage level in samples caused by thermal shock.

AB  - The thermal stability of the refractory material with the Al 2 O 3 content of 42 mass-% was investigated. Water quench tests (JUS.B.D8.319.) were carried out. The dynamic Young modulus of elasticity was calculated using measured values of longitudinal (Vp) and transversal (Vs) velocities. Mechanical characteristics were considered such as compressive strength, dynamic modulus of elasticity and resistance parameters resulting from resonance frequency measurements as well as ultrasonic velocity. An analysis of the thermal shock behaviour of the samples based on the obtained results is provided.

AB  - Thermal stability of the refractory material with the content of 42 % Al2O3 was investigated. Water quench test (JUS.B.D8.319.) was applied. Photographs of the samples before cycling, and after some number of cycles were given. Dynamic Young modulus of elasticity was calculated using measured values of longitudinal (Vp) and transverzal (Vs) velocites. Values of dynamic Young modulus and changing in compresive strength during testing were presented as function of the measured number of quench experiments. Analysis of the thermal shock behavior of the samples based on the obtained results was given.

Uzorci su snimljeni pre ispitivanja, kao i posle odredjenog broja ciklusa. Dinamički Jungov modul elastičnosti je odredjen na osnovu izmerenih brzina logitudinalnih (Vp) i transverzalnih (Vs) talasa. Pretstavljene su vrednosti dinamičkog modula elastičnosti i promene pritisne čvrstoće u funkciji broja ciklusa ispitivanja termostabilnosti. Na osnovu dobijenih rezultata data je analiza praćenja ponašanja vatrostalnog uzorka izloženom termošoku.

AB  - The aim of the study was to obtain water soluble carboxymethylcellulose (CMC) with a high degree of polymerization (DP  gt  600) and high degree of substitution (DS  gt  800), in industrial conditions, from easily degradable eucalyptus cellulose. The influence of temperature and of the NaOH:MCAA molar ratio cellulose on the structural and degradative changes in cellulose macromolecules during the process was investigated using ethanol as the reaction medium. The structural transformations during alkalization and etherification were investigated by X-ray diffraction. The degradative changes in the macromolecule were followed by determining the degree of polymerization. The degree of substitution and other chemical characteristics were determined by standard analytical methods. The thermal behaviour of the samples was studied by using a Perkin Elmer DSC-2 instrument. The rheological properties of the CMC solutions were also studied.
