水泥粒度分布对水泥性能影响的研究进展

Reasearch Progress of the Influence of Particle Size Distribution on the Properties of Cement

从两个方面总结了水泥粒度分布对水泥性能影响的研究进展,一方面总结了反映水泥颗粒群整体情况的特征参数比表面积S、特征粒径x′和均匀性指数n对水泥性能的影响;另一方面总结了不同粒径区间水泥颗粒的性能。介绍了描述水泥粒度分布的RRB方程和Fuller曲线,综述了理论上粒度分布对水泥性能的影响情况,认为水泥的粒度分布是与其性能有明确定量关系的细度参数,是水泥粉磨细度控制的最终目标。

The effect of the particle size distribution on the properties of cement is summarized in two aspects. On the one hand, the effect of different characteristic parameters such as specific surface area S, characteristic particle size x＇and uniformity factor which reflect the overall situation of cement particle size distribution on the properties of cement is summarized. On the other hand, properties of cement in different particle size ranges are summarized. RRB equation and the Fuller curve which are used to discribe the particle size distribution of cement is introduced. And in- fluence of particle size distribution on properties of cement in theory is simply introduced. It is considered that particle size distribution is a fineness parameter which has a clear quantitative relationship with properties of cement and it is the ultimate goal of fineness control for cement grinding.
