- Abstract
LPEG monomer is a new type of polycarboxylate superplasticizer monomer, has higher reactivity than ordinary polycarboxylate macromonomer in recent years, synthetic PCE has better working performance. Using a new type of ethylene glycol monovinyl ethoxylate (LPEG), acrylic acid (AA) and hydroxyethyl acrylate (HEA) as a polymerization monomer, Synthesis of PCE under low temperature redox initiation system, experiment and discuss the effects of reaction temperature, FeSO4 dosage, acid-ether ratio, reducing agent and chain transfer agent dosage on PCE performance. Compared with the traditional PCE, the new PCE has better slump retention and concrete workability.
