Abstract

The shortcoming of polycarboxylate superplasticizer could delay the early strength of concrete, this limit its use in winter.In order to satisfy the application of polycarboxylate superplasticizer in the early strength constructional buildings.TEA was introduced into molecular chain of polycarboxylate superplasticizer, and the early-age strength of (3d and 7d) were investigated to find the optimal component.This type early-strength polycarboxylate superplasticizer has high superplasticizer, and it didn't impact the slumps and slump flow.
