| Abstract: | The influence of MgO on the formation of Ca3SiO5 and 3CaO·3Al2O3·CaSO4 minerals in alite-sulphoaluminate cement is reported in this paper. The results show that adding a suitable amount of MgO can lower the clinkering temperature, promote the formation of Ca3SiO5 and 3CaO·3Al2O3·CaSO4 minerals, and help in the coexistence of the two minerals in the clinker. MgO may obviously decrease the formation of Ca3Al2O6, and increase the SiO2 content incorporated into the interstitial phase. |
