In this work, four BACSA clinkers with different compositions (belite ~ 70-55 wt %, alite ~ 10-15 wt % and ye’elimite ~ 10-15 wt %) were synthesized (at laboratory scale). Lime, gypsum, kaolin and sand were used as raw ...

Belite Calcium SulfoAluminate (BCSA) eco-cements were developed as OPC substitutes since in their production release 22% less CO2 than OPC. BCSA eco-cements contain belite as main phase (>50 wt%) and ye'elimite as secondary ...

The main objective of this work is to understand the effect of the addition of fly ash (0, 15 and 30 wt%) in the hydration of a BACSA cement paste (water/cement=0.4) prepared with 12 wt% of anhydrite. The pastes were ...
