Polyethylene glycol monomethyl ether methacrylate serves as the active monomer in polycarboxylic acid-based water-reducing agents. These agents represent the third generation of high-performance water reducers, evolving after conventional water reducers (such as calcium lignosulfonate) and high-efficiency water reducers (such as naphthalene-based agents).This type of superplasticizer offers low dosage requirements, high water-reduction rates, no segregation or bleeding, excellent slump retention in concrete, and good compatibility with cement, admixtures, and other additives.They effectively reduce early-stage autothermal temperature rise in concrete and minimize temperature cracking in mass concrete. Their molecular structure offers greater design flexibility, unlocking higher potential for performance enhancement. They provide the technical foundation for promoting the use of high-volume industrial byproducts like fly ash, slag, and steel slag.
