Abstract: This paper elaborates the mechanism of polycarboxylate-based superplasticizer on cement concrete and, in particular, describes the effect of this type of admixture on pore structure and interface state of cement based materials. Experimental results demonstrate that the effect of polycarboxylate-based superplasticizer on concrete microstructure is largely influenced by its molecular structure, graft group and graft quality. Using the polycarboxylate-based superplasticizer with superior performance can effectively optimize the pore structure of cement concrete.
