Synthesis and characterization on anti-clay polycarboxylate superplasticizer in concrete
Case Studies in Construction MaterialsTo address the issues of low anti-clay performance and high adsorption of ordinary superplasticizer in concrete applications, a novel anti-clay polycarboxylate superplasticizer (Abbreviated as KN-G superplasticizer) was developed.

Synthesis and performance of polycarboxylate superplasticizer with ester monomers
ce/papersAbstractRelevant studies have shown that ester monomers improve concrete mud resistance, slump retention, fluidity and so on more obviously. In this paper, a series of polycarboxylate superplasticizer were prepared by using polyglycol maleic anhydride (PGA), phosphoric acid ester of capped amide (PCA), and methoxy polyglycol acrylate (PGMA) as the ...

Molecular Behavior of Different Polycarboxylate Superplasticizers
IOP Conference Series: Materials Science and Engineering, 2019 Abstract Four different types of polycarboxylic superplasticizers were synthesized by using different macromonomers, and then the molecular behavior of GPC, infrared, nuclear magnetic, cement hydration heat and micromorphology were characterized. The results showed that different types of PCEs have different molecular behaviors.
