Abstract

The polycarboxylic slump-retaining admixture was synthesized by methyl allyl polyoxyethylene ether (TPEG) and unsaturated carboxylic acid in redox system. The factors influencing on performance of polycarboxylic slump-retaining admixture such as temperature, reaction time, acid alcohol ratio, the amount of initiator and molecular regulator were researched. It show that the performance of slump-retaining agent is best when the ratio of acid to alcohol is 1.75:1, amount of initiator is 0.56%, molecular weight regulator dosage is 0.28%, reaction time is 1.5h, and reaction temperature 60 .The molecular structure of polycarboxylate slump-retaining were characterized by infrared spectroscopy.
