1) Polycarboxylate SJC small dosage, 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. Through the observation of workability and appearance, mixed with the polycarboxylic acid concrete admixture no bleeding phenomenon, concrete testing air content of about 4.1%, and the apparent microscopic bubble, Fangchenggang polycarboxylate liquor, 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. Polycarboxylate superplasticizer is the second timber of calcium as a representative of ordinary water reducer and naphthalene-based superplasticizer development, represented the third generation of superplasticizer, polycarboxylate liquor, is currently the world On the forefront of the highest scientific and technological content, the best prospects, the best overall performance of a superplasticizer. Polycarboxylate superplasticizer is an independent company to develop a new generation of environmentally friendly and efficient water reducer, the liquid is pale yellow or brownish red transparent liquid. The major components of a molecular weight of 5,000 to 50,000 polycarboxylate polymer products. By comparison with the performance of similar products at home and abroad show that polycarboxylate superplasticizer in technical performance, cost-effective ways to achieve the current international advanced level. It is a water reduction, slump, enhancement, anti-shrinkage and environmental protection equivalent to a series of water-reducing agent having excellent properties, the North Sea polycarboxylate mother liquor, can solve high-strength, high-performance concrete viscosity, good workability weakness , it is the preparation of high-strength, ideal for high performance concrete admixtures. Admixture with a variety of multi-functional additives mixed together, such as pumping agent, early strength, impermeability waterproofing agents, retarders and the like.
