Polycarboxylate superplasticizer as a representative of the third generation superplasticizer, water reducer is the dominant current direction of development of the industry, in addition to a green, high strength, high water reducing rate, low dosage, dispersion and dispersion retention and good performance advantages, its other main feature is a large degree of freedom of molecular structure, the Nanjing-acid liquor manufacturers, can get excellent performance expected by the molecular structure of a multi-purpose design superplasticizer [1]. Current national polycarboxylate superplasticizer for more research and application, with Japan to promote the application of the more successful. In 1986 Nippon Shokubai Co., developed the first successful Polycarboxylate superplasticizer has a certain proportion of hydrophilic functional groups, Harbin polycarboxylate liquor manufacturers, and then gradually applied in concrete engineering 1) Polycarboxylate SJC doping very small, high water reduction in concrete, the optimal dosage of 0.9% -1.1% by weight of cementitious material. 2) were mixed with concrete mix workability of the two types of poly-carboxylic acid and naphthalene based superplasticizer significantly different. By observing the workability and appearance, polycarboxylate liquor vendors, incorporating the polycarboxylic acid concrete admixture no bleeding phenomenon, concrete testing air content of about 4.1%, and the apparent microscopic bubble, concrete has a good cohesiveness, pouring good; and mixed naphthalene superplasticizer concrete workability described in Test No. slump (mm) Setting time h Compressive Strength (MPa) 0h 1.5h 7d 28 11 195 good workability 8:25 10:20 12 130 25.8 40.9 good workability 10.30 25.4 40.2 8.30 200 150 13 185 125 viscous 8:25 10:25 25 39.3 slightly bleeding phenomenon, test the gas content of approximately 2.8 %, there are more large bubbles. From the concrete appearance quality is better than watching the polycarboxylic acid admixture of naphthalene superplasticizer.
