1. Polycarboxylate at low dosage high water reduction can be achieved and good workability, Yishui polycarboxylate liquor, and can reduce the amount of cement and improve fly ash, slag gelling material ratio, serve to reduce the cost of action. 2, polycarboxylates low alkali content, concrete help to curb harmful alkali aggregate reaction, the concrete experimental research, it formulated concrete workability traditional naphthalene water reducing agent can not be reached. 3, a small net loss polycarboxylate paste fluidity, but it formulated concrete slump poor performance slump performance than in naphthalene series, we hope to continue to study the future concrete enthusiasts. 4, doped poly-carboxylic concrete testing air content of about 4.1%, polycarboxylate liquor formula, apparent microscopic bubble, polycarboxylate liquor prices, concrete has good cohesion, poly-carboxylic acid liquor equipment, casting sex good; and naphthalene superplasticizer concrete mixed in a little bleeding phenomenon, test the gas content of approximately 2.8%, with more large bubbles. 5, through experiment and calculation, poly carboxylic acid water reducing concrete cost less than varieties of naphthalene, used in modern concrete application prospects. Synthesis of Polycarboxylate superplasticizer copolymerization reaction can be divided into the following three: ① direct polymerizable monomer copolymerizable: This method is generally first prepare a polymerization-active monomer (usually methoxy polyethylene glycol methacrylate), and then mixed with a certain proportion of the monomer solution polymerization directly from the system. ② aggregated functional method: This method is mainly the use of existing polymer modified, using known molecular weight polyethylene acid, in the catalyst at a higher temperature and polyether grafting by esterification. ③ situ polymerization and grafting: The law is to compensate for the defect aggregation after functional method developed to polyether carboxylic acids unsaturated monomer polymerization reaction medium.
