Abstract
A slump retaining polycarboxylic acid superplasticizer. A weight average molecular weight of the superplasticizer is 20,000-80,000. The slump retaining polycarboxylic acid superplasticizer is prepared by performing polymerization reaction on a monomer A, a monomer B, a monomer C and a monomer D in an aqueous solution in the presence of a redox initiator, wherein a molar ratio of (the monomer A+the monomer B):the monomer C:the monomer D is 1:(3-8):(4-12), and a molar ratio of the monomer A to the monomer B is 1:(1-4).
