Abstract
In this paper, 4-hydroxybutylvinyl polyoxyethylene ether (VPEG), methacrylic acid (MA) and methylene phosphate (MEPA) are used as main raw materials to synthesize a hexa-carbon polycarboxylate superplasticizer with high workability under the action of an iniator. The test results show that the superplasticizer has high water-reducing rate and good slump-retention, and its workability is greatly increased, which can be used in practical concrete projects that have high requirements.
