摘要
本文着重研究了WH-Ⅱ型超缓凝剂对硅酸盐水泥水化、水化热、水化放热速率、凝结时间、强度等的影响,运用XRD、SEM对硅酸盐水泥的水化过程进行跟踪测试,结果表明适量使用WH-Ⅱ型缓凝剂可以得到合适的缓凝效果和增强作用。
This paper investigated the effects of WH-Ⅱ super set-retarding agent on the hydration, the heat of hydration, the setting time and strength of Portland cement. The process of hydration of Portland cement was determined by using XRD and SEM. The results show that appropriate amount of WH-Ⅱ super set-retarding agent added to the Portland will be effective on retarding the setting time and improving the strength of Portland cement.
