The influence of gypsum content on water demand, time of setting, strength and shrinkage of high Performance cementitious material is tested as warrant for optimizing gypsum content.
试验研究了石膏的掺量对高性能胶凝材料的需水量、凝结时间、强度、收缩性的影响，以此作为优化石膏掺量的依据。
The influence of content of coal gangue on cementitious properties was investigated. The hydration products of the cement were characterized by XRD, SEM etc.
研究了活化煤矸石对水泥性能的影响，借助XRD、SEM等测试方法分析了活化煤矸石作水泥混合材的作用机理；
The optimum content of silica fume is 0.25, and the lowest water to cementitious materials ratio is 0.18.
此时硅灰的最佳掺量为水泥质量的0.25倍，且水胶比并不是越低越好，最佳水胶比为0.18。
