摘要

The formation and strength of Portland cement clinker containing calcium sulphoaluminate (C₄A₃S̄, C=CaO, A=Al₂O₃, S̄=SO₄^2-), which was synthesized with industrial reagents as raw materials, were studied. The process of mineral formation was analyzed by X-ray diffraction and thermogravimetric-differential scanning calorimetry. The influence of ZnO on the properties of clinker and solid solutions were discussed. The results show that tricalcium silicate (C₃S, S=SiO₂) and calcium sulphoaluminate (C₄A₃S̄) minerals can form and coexist in clinkers sintered at low temperature by the addition of ZnO to the raw material, and increase the strength of Portland cement clinker containing C₄A₃S̄. The decomposition temperature of C₄A₃S̄ can be lowered by the addition of excessive ZnO into the raw materials.
