| Abstract: | This paper investigated the effects of WH-Ⅱsuper 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-Ⅱsuper set-retarding agent added to the Portland will be effective on retarding the setting time and improving the strength of Portland cement. |
