| Abstract: | Ettringite formation is very important for the fluidity and fluidity loss during early hydration of cement paste. In this paper, the various effects of superplasticizers on the crystallization of the ettringite were reviewed. The reasons of the two different effects （restrained by adsorption and promoted by adsorption）were analysed. |
