为了了解波特兰水泥中的水化硅酸钙(C-S-H)的微观结构,对有无含添加剂superplasticizers(SPs)、从5天到68天的不同老化时间的波特兰水泥样品的X光散射实验,实验数据结果分析表明C-S-H中钙硅层间距的大小是0.98±0.01nm,结果说明波特兰水泥样品中C-S-H中钙硅层间距与样品是否含SPs以及样品的老化时间无关。
In order to understand the microstructure of hydrated calcium silicate (CSH) in Portland cement, X-ray scattering of Portland cement samples with different aging times from 5 days to 68 days with or without superplasticizers (SPs) Experimental and experimental data analysis shows that the size of the CSG in the CSH is 0.98 ± 0.01nm. The results show that the spacing of the CSG in CSH in Portland cement samples is independent of whether the samples contain SPs or not and the aging time of samples.
