摘　　要：研究了早期受冻环境下铝酸盐水泥复合普通硅酸盐水泥砂浆试件的力学性能及其微观形貌的变化。结果表明:纯铝酸盐水泥体系具有良好的早期抗冻性能,但其与普通硅酸盐水泥复合时,普通硅酸盐水泥掺加比例0～70%时,其早期抗冻性能会有明显下降趋势;而在70%～100%时又呈现上升趋势,但增加幅度较小。铝酸盐水泥低掺量掺入会延迟硅酸盐水泥的水化,导致其复合体系早期抗冻性降低。The mechanical properties and morphology of aluminate cement composite ordinary Portland cement mortars under early freezing conditions were studied. The results showed that the pure aluminate cement system have a good early frost resistance, but when it was mixed with ordinary Portland cement, the early frost resistance of composite cement would obviously decrease when the proportion of ordinary Portland cement was 0-70%. When the proportion of ordinary Portland cement was 70%-100%,the early frost resistance of composite cement would show an upward trend,but the increase was small. The low dosage of aluminate cement would delay the hydration of Portland cement, and lead to the decrease of the early frost resistance of the composite system.
