We summarize the causes and countermeasures of massive concrete cracking, and propose that crack resistance of massive concrete can be effectively improved by low-heatPortlandcement.
The results show that AS cement possesses high early strength, low hydration heat and durability, but its shrinkage rate is higher than that of portlandcement.
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;

For massive concrete construction, the low hydration heatcement like the slag Portland cement is often used to facilitate temperature rise control in the concrete.
