Influence of Polycarboxylate Superplasticizers with Different Functional Units on the Early Hydration of C<sub>3</sub>A-Gypsum

Influence of Polycarboxylate Superplasticizers with Different Functional Units on the Early Hydration of C<sub>3</sub>A-Gypsum

Influence of polycarboxylate superplasticizers (PCs) with different functional units on the hydration heat and hydration products of C<sub>3</sub>A-gypsum was investigated. Three kinds of PCs with different monomers were discussed. It was seen that PCs mainly shortened the induction stag...

It was seen that PCs mainly shortened the induction stage of C<sub>3</sub>A-gypsum hydration, and the amount of remaining gypsum was related to the duration of the induction stage.
