Abstract

The aim of this study was to investigate the effect of EPEG with different molecular weight on the early strength of polycarboxylic acid superplasticizer. Through experimental testing and analysis, it was found that the early strength of polycarboxylic acid superplasticizer could be improved by appropriately increasing the molecular weight of EPEG, and the influence of EPEG molecular weight on the 1-day early strength of the synthesized polycarboxylic acid superplasticizer was more obvious at 20℃ than at 5℃, but the water reducing and dispersion performance of the high molecular weight EPEG synthesized polycarboxylic acid superplasticizer would be decreased.
