摘　　要：比较了两种不同矿物组成、不同颗粒级配的高C3S水泥的抗压强度和水化热与颗粒组成的关系。试验发现增加粉磨时间,水泥的抗压强度和水化放热量增加;抗压强度与平均粒径和均匀性系数的乘积(X·n)呈线性关系;抗压强度与0～30μm颗粒含量有明显的规律性。传统认为的水泥强度主要提供者3～30μm颗粒含量与抗压强度和水化热没有明显的规律性,因为增加粉磨时间3～30μm颗粒含量变化不大。The relation between compressive strength, hydration heat and partic le size distribution of two kinds of high C3S cement with different mineral comp ositions and different grain grades was compared. The result showed that compres sive strength and hydration heat increased as the grinding time did. It was line ar relation between compressive strength and the product of average particle siz e(X) and uniformity coefficient(n). It wasn’t the content of particle whose siz e ranged from 3μm to 30μm but the content of particle whose size ranged from 0 to 30μm which had perfect rule to the compressive strength, because the conten t of particle changed little as the grinding time increased.
