MAC cementing material was in-situ synthesized with different ratios of raw materials and sintering temperatures. The raw materials include hydrated lime, magnesite and alumina. X-ray diffraction analysis indicates that the major mineral phases in the MAC are monocalcium aluminate (CA), magnesium aluminate spinel (MA) and calcium aluminate (C7A12). The relative contents of the mineral and amorphous phase were simply calculated based on the relative diffraction peaks and MgO-Al2O3-CaO ternary phase diagram. SEM and EDS analysis indicate that the MAC cementing material includes layered structured CA, long strip C7A12 and octahedral MA.
