摘要

Calcium sulphoaluminate (3CaO·3Al₂O₃·CaSO₄, C₄A₃S̄) was prepared with chemical reagents CaCO₃, Al₂O₃, CaSO₄·2H₂O. The formation mechanism of C₄A₃S̄ was investigated by chemical analysis, X-ray diffraction, differential scanning calorimetry-thermogravirnetry and scanning electron microscopy and energy disperse spectroscopy. The results show that C₄A₃S̄ is formed in three kinds of ways. C₄A₃S̄ is formed mainly by solid reaction of CaO, Al₂O₃ and CaSO₄ below 1100°C. Other two ways are either through 12CaO·7Al₂O₃ (C₁₂A₇) or monocalcium aluminate (CA) act as the interphase in the formation of C₄A₃S̄ above 1100°C.
