【摘要】 实验室测试了粗、细组分分别粉磨的多组水泥试样的颗粒级配和水泥性能。结果表明，在８～２４μｍ和３２～４８μｍ两个粒径范围内的颗粒含量高的水泥试样，其强度也高。即水泥颗粒的分布尽量控制在几个不同的范围，且每一范围越小（颗粒越集中），对水泥强度越有利。更多还原

【Abstract】 Abstract The particle distribution and properties of several cement samples were tested which were composed of component with different fineness by separate grinding in the laboratory The results showed that,the cement containing more particles with sizes ranging from 8～24μm and 32～48μm had higher strength than that of other samples That indicated the particle distribution of cement should be controlled in a few ranges,and the more narrow the ranges were,the higher the strength would be更多还原
