Polycarboxylate superplasticizer(PCE) is a kind of high-efficiency water reducer that appeared in the early 1980s. It is mainly used for concrete. PCE concrete admixture belongs to polymer surfactants. Therefore, it can also be used in other paste-like materials, such as gypsum and ceramics, to reduce water content. PCE based admixture generally has a water reduction of more than 25% in concrete and has good compatibility with the base material. Adding the amount of pce admixture into concrete, the slump and expansion loss of the concrete are small, the fluidity is large, and the water retention, cohesiveness, and climate adaptability all perform well.
