Polycarboxylate superplasticizer as a representative of the third generation superplasticizer is the main direction of development of the industry in today's water reducer, Tianjin ready-mixed mortar admixtures, in addition to a green, high strength, high water reduction, low dosage, dispersion and dispersion retention and good performance advantages, its other main feature is the molecular structure of the large degree of freedom, you 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, ready-mixed mortar admixtures, which promote the use of more successful in Japan. In 1986 Nippon Shokubai Co., developed the first successful Polycarboxylate superplasticizer has a certain proportion of hydrophilic functional groups, followed by the gradual application of polycarboxylate superplasticizer with a small dosage in concrete projects, efficient water reducing dispersant , low-alkali and other characteristics, can significantly improve the workability of concrete, fluidity concrete strength and concrete and so on. This paper describes Polycarboxylate and Comparative study on naphthalene superplasticizer proved Polycarboxylate preparation of concrete not only have a clear technological advantage, and the cost is also lower than naphthalene superplasticizer should be widely applied, but needs improve polycarboxylate admixtures entraining high slump resistance and properties of concrete issues. Hebei mixed mortar admixtures, ready-mixed mortar admixtures, building materials, high-strength high-strength building materials provided by the Linyi City Limited. Linyi high-strength building materials Limited (www.lygqjc.cn) strong, credible, concrete and Shandong Linyi products and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead high-strength construction materials into the brilliant and you work for a better future!
