Study on the Preparation and Performance of Hexa-carbon Polycarboxylate Superplasticizer with High Workability

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 has water-reducing rate good slump-retention, its is greatly increased, which can be in practical concrete projects have requirements.
