研究了不同结构单元的聚羧酸减水剂对C3 A石膏水化热和水化产物的影响。讨论了三种不同单体的聚碳酸酯。结果表明，聚碳酸酯主要缩短了C3 A-石膏水化的诱导期，而剩余石膏量与诱导期的持续时间有关。加入PC的样品的第二热流峰高于空白样品。此外，PC插层发生在水化。
Influence of polycarboxylate superplasticizers (PCs) with different functional units on the hydration heat and hydration products of C3A-gypsum was investigated. Three kinds of PCs with different monomers were discussed. It was seen that PCs mainly shortened the induction stage of C3A-gypsum hydration, and the amount of remaining gypsum was related to the duration of the induction stage. The second heat flow peak of the sample with PCs was higher than that of the blank. Moreover, PC intercalation occurred during the hydration.
