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%. ...
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 ...
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 ...
