Abstract

This paper mainly studies the influence of clinker mineral composition on the performance (flow variability and expansion performance, hole structure, etc.) of silicate cement. The experimental results show that the shear stress of silicate cement slurry body consisting of different minerals is different with the rheography curve of shear rate, and the linear relationship between the two belongs to Bingham rhesino equation, the expansion rate is also quite different, the expansion rate of D mineral composition is the largest, and the distribution of the aperture of different minerals composition is different, the size of the gap and the degree of hydracy are different.

摘要

本文主要研究熟料矿物成分对硅酸盐水泥性能（流动可变性和膨胀性能、孔结构等）的影响。实验结果表明，不同矿物组成的硅酸盐水泥浆体的剪切应力随剪切速率的流变曲线不同而不同，两者之间的线性关系属于Bingham rhesino方程，膨胀速率也有较大差异，膨胀D类矿物组成比例最大，不同矿物组成的孔隙分布不同，孔隙大小和水化程度不同。
