Test and calculation results show that the anti-crack properties of No. 425 lowheatcement concrete are obviously superior to those of No. 525 medium heat cement concrete;
试验和计算结果表明：425号低热水泥混凝土的抗裂性能明显比525号中热水泥混凝土的好；

For massive concrete construction, the low hydration heatcement 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。
