Originální abstrakt

The effect of temperature on flow properties and viscoelastic properties of brick powder based pastes prepared by alkaline activation of red clay brick waste is monitored in this paper. A different effect of temperature with respect to its classic rheological influence was ascertained. Elevated temperature has a considerable impact on the yield stress, viscosity and thixotropy of brick pastes, which turn to be more pseudoplastic and rheopectic. Raising temperature accelerates the geopolymer curing kinetics and contributes to the more rigid structure of the resulting geopolymeric gel.
