| Abstract: | A polycarboxylate superlasticizer was synthesized from acrylic acid,acrylamide, Sodium methallyl sulfonate,and a different molecular weight polyethylene glycol allyl by the radical polymerization.Its applied performance in concrete was tested.The results showed that the wsuperlasticizer has excellent properties,such as a high water reducting rate,good workability,greatly enhance the early strength of concrete,and early strength is targeted to the requirements of high-performance concrete. |
