1·For massive concrete construction, the low hydration heat cement like the slag Portland cement is often used to facilitate temperature rise control in the concrete.
大体积混凝土施工时常选用水泥水化热较低的矿渣硅酸盐水泥等以利于混凝土温升控制。
2·The results show that AS cement possesses high early strength, low hydration heat and durability, but its shrinkage rate is higher than that of portland cement.
结果表明，碱-矿渣水泥具有早强、高强、低水化热和高耐久性等优良性能，但是干缩较大；
3·We summarize the causes and countermeasures of massive concrete cracking, and propose that crack resistance of massive concrete can be effectively improved by low-heat Portland cement.
总结分析了大体积混凝土易产生裂缝的原因及应对措施，指出使用低热硅酸盐水泥可有效改善大体积混凝土的抗裂性能。
