Abstract

In order to solve the problems of high viscosity and slow flow rate of high-strength concrete. Using EPEG type low molecular weight large monomer as the main raw material, the effects of the acid to ether ratio, the amount of bottom liquid acrylic acid, the amount of chain transfer agent, and the amount of reducing agent on the flow properties of the viscosity reducing polycarboxylic superplasticizer were investigated. The results showed that the viscosity reduction effect of VR-PCE was the best when the acid to ether ratio is 3.5, the bottom liquid acrylic acid dosage is 6% of the total acrylic acid dosage, the chain transfer agent dosage is 0.30% of the EPEG dosage, and the reducing agent dosage is 0.25% of the EPEG dosage.
