Due to the important contribution of concrete superplasticizer modified terms, after its application to become reinforced and prestressed concrete, concrete history of the development of the third major breakthrough. In the development and application of superplasticizer as a symbol, the concrete technology into a plastic, dry and hard to fluidized third generation. In the early 1990s, the United States first proposed the concept of high-performance concrete (HPC), which called for concrete with high strength, high mobility, high performance and durability of ready-mixed mortar admixture plant in Jiangsu, high-performance concrete water reducer made for more high demand of ready-mixed mortar admixture plant, requires superplasticizer having a water reducing rate, high fluidity and slump loss and other small features over time. Some new superplasticizer got rapid development and application, such as poly shuttle acid-based, amino acid based superplasticizer. 1. Polycarboxylate at low dosage high water reduction can be achieved and good workability of ready-mixed mortar admixture plant in Zhejiang, and Shanghai can reduce the amount of cement mixed mortar admixture plant, improve powder ash, slag cementitious 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%, and the apparent microscopic bubble, concrete has good cohesion, pouring good; and naphthalene superplasticizer mixed concrete in a slight bleeding phenomenon, Test air content of about 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.
