    Cement pastes + wastes were prepared in 25% and 50% proportions and setting time, water absorption and compressive strength were determined. The results indie that although the wastes do not show any significant variation in the elementary chemical composition, changes in the values of compressive strength were observed in the pure cement paste.

    There are several ways to increase the mechanical strength of cement. It is common to use cement additives that increase the mechanical strength by chemical activation, without changing the cement surface and particle size distribution. Alkanolamines are frequently used and are able to increase the compressive strength (at different or all age) by max. five MPa. Typical examples are SikaGrind ...
