Investigation of high temperature behavior and sintering mechanism of fly ash based concretes
(Procema SA, 2014)
Four types of refractory concretes were studied at various temperatures ranging from ambient to adopted maximal 1400 degrees C. The concretes had same matrix composition: K concretes were based on corundum aggregate; B ...
Comparative kinetic study of mechanical activation process of mica and talc for industrial application
(Elsevier Sci Ltd, Oxford, 2014)
Mica and talc have wide areas of application as a raw material in a number of industrial branches. Mechanically activated mica has specific applications such as: capacitors, insulators, and pearlescent pigments. Talc is ...
The influence of silica fume and curing regime on some properties of concrete
(Revista Romana de Materiale/ Romanian Journal of Materials, 2014)
The investigation of posibilities of concrete structure modification by silica fume to improve concrete properties was presented in this report. Percentage of silica fume in regard to cement varied between 0% and 20%. ...
Identification of low cycle fatigue parameters of high strength low-alloy (HSLA) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Investigation of the mortar and concrete resistance in aggressive solutions
(Univ Osijek, Tech Fac, Slavonski Brod, 2014)
Testing the influence of two aggressive solutions - sulphate and nitrate on mortar and concrete was presented in this paper. Experimental work included testing of mortar prisms with 5 % special admixture. Also, four types ...
Drying kinetic simulation of clay tiles made from the raw material having less clay fraction
(Trans Tech Publications Ltd, 2014)
In order to describe the internal moisture rate and to take all different mechanisms of moisture movement into account, it is suitable to use effective diffusivity as a measure of moisture rate, irrespectively of the ...
Prediction and Optimization of Heavy Clay Products Quality
(Wiley Blackwell, 2014)
The effects of chemical composition, firing temperature (800-1100 °C), and several shape formats of laboratory brick samples on the final product quality were investigated. Prediction of the final laboratory products ...
Mechanical Activation as Sintering Pre-treatment of Talc for Steatite Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
The effect of vibratory mill induced mechanical activation on the change of the particle size, crystallinity and the phase transformations of the minerals present in the activated material, was studied with the purpose of ...
