| 摘 要： | 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。 |

| Abstract: | In order to understand the microstructure of the calcium silicate hydrate(C-SH),the samples of Portland cement paste with/without superplasticizers(SPs)at different aging time from 5days to 68days were studied by the X-ray scattering.The experimental data analysis shows that the interlayer space between calcium silicate layers within C-S-H is 0.98±0.01nm.The result indicates that the interlayer space between calcium silicate layers within C-S-H in Portland cement is constant regardless of what aging time is and whether the paste is with/without SPs. |
