Cement Composites Modeling Using Amorphous Kaolin

Abstract

Cement based composites (concrete and mortar) are widely used in building industry, owing their popularity to huge production rate of cement. Nevertheless, cement production was found to have several negative environmental impacts. This is the reason why more and more alternative binders, like amorphous kaolin, are investigated and whenever possible implemented, with respect to the rules of energy efficiency. Three series of mortars were made, with and without amorphous kaolin, and then investigated both in fresh and in hardened state, as well. Positive impact of substitution of cement with amorphous kaolin was detected, especially in fresh state (improvement of consistence).
