Abstract:
Dolomite (CaMg(CO3)2) is a promising alternative to the commonly used limestone as an SCM. The present study investigated the reaction of dolomite in various combinations with metakaolin as replacement of 40 %wt of Portland cement clinker in composite cement pastes. The microstructure and phase assemblage of the paste samples cured at 20 °C, 38 °C or 60 °C for up to 1 year was investigated with TGA, XRD, SEM-EDS and MIP. It could be shown, that in samples without any metakaolin approx. 60...     »
