Polycarboxylate superplasticizer is a newly developed type with a "flowing" structural feature. After being added to the concrete, the mixing degree of the mixture in the concrete can be enhanced, and a certain amount of fly ash can be added to the mixtur
The polycarboxylate water-reducing agent is a graft copolymer having a comb-like molecular structure, the main chain is an alkyl carbon chain having a carboxyl functional group, and the side chain is a polyoxyethylene (and/or polyoxypropylene) structural
At home and abroad, research on improving the early strength of polycarboxylate superplasticizers mainly focuses on the following two aspects.
Polycarboxylate water reducing agent has been continuously developed in recent years, and its synthesis conditions have changed from high temperature conditions to low temperature conditions, and its performance has also evolved from a single function of
High performance polycarboxylate water reducer with high dispersibility, good retention performance, low concrete shrinkage and strong molecular structure.In addition, the polycarboxylate water reducing agent does not use formaldehyde and other outstandin
