摘   要：本研究着力于超硫酸盐水泥在大体积混凝土中的应用，通过研究其物理性能、力学性能，分析在混凝土中应用的可行性；通过测试水化温升，分析在大体积混凝土中的应用优势；通过扫描电镜（SEM）分析水化产物形貌。试验结果表明，超硫酸盐水泥混凝土流动性能较好，且其工作性能优于普硅水泥配制的混凝土。对于超硫酸盐水泥体系的混凝土强度，标准养护条件下稍高于在常温条件下养护的试块。随着龄期增长，混凝土抗压强度都在增长，且增长速率逐渐降低。超硫酸盐水泥体系的强度低于普硅水泥体系，但是后期强度增长速率明显高于普硅水泥体系。超硫酸盐水泥体系的水化温升低于普硅水泥。超硫酸盐水泥体系的主要水化产物为“鱼鳞片”状的水化硅酸钙和钙矾石。

Abstract: The use of supersulfated cement (SSC) in mass concrete was studied. The physical properties and mechanical property were tested. Contrasting with the common cement, the temperature rise of hydration and the heat of hydration to obtain the advantage of SCC were analyzed, which could provide the basis for the use of SCC in mass concrete. The micro properties were tested through scanning electron microscope (SEM). The test shows that the SSC shows better working performance than ordinary cement. The compressive strength of SSC under standard curing condition is higher than that under room curing condition. The compressive strength of SSC is increasing with time and the rate of increasing is decreasing. The temperature rise of hydration of SSC is lower than that of ordinary cement. Different with the ordinary cement, the main hydrated products of SSC are ettringite and scaly calcium silicate hydrate.
