1) Polycarboxylate SJC small dosage, high water reduction in concrete, Heilongjiang polycarboxylate liquor manufacturers, the best content 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. Through the workability and appearance observation, mixed with poly-carboxylic acids concrete admixtures no bleeding phenomenon, Jiangsu polycarboxylate liquor factory, 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 good workability 8:25 10:20 195 130 25.8 40.9 12 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% polycarboxylate liquor factory, there are more large bubbles. From the concrete appearance quality is better than watching the polycarboxylic acid admixture of naphthalene superplasticizer. Each group of cement dispersion play a different role, it is generally believed that negatively charged sulfonic acid groups and carboxylic acid groups can be adsorbed onto the surface of cement particles, play the anchor role, but also play a role in electrostatic repulsion. Long side extending in the solution plays a strong steric hindrance. Steric hindrance dispersion of cement particles is strong, Shanghai-acid liquor manufacturers, and the impact of the electrolyte as sensitive to electrostatic interaction unlike so polycarboxylate superplasticizer has a good dispersion of adaptability of cement is better.
