1995 Japan after polycarboxylate superplasticizer superplasticizer use amounted to an amount of 80%, in 1995 included JISA6024 national standards. In contrast to the United States and Europe polycarboxylate high performance water reducer Application late in Japan, 1997 Fifth International Conference on concrete admixtures scholars in Europe and America has published more than 10 articles on polycarboxylate can be reduced agent's papers. Currently, about superplasticizer developed more than 100 US patents have been. Research and domestic research is more concerned about the mechanism of these compared to the impact superplasticizer on cement hydration and paste microstructure, as well as fresh concrete water reducing performance and slump retention performance, entraining concrete, segregation bleeding water, condensation and pumpable some overall performance. Since the 20th century, since the late 1990s, China's research institutes, universities, the strength of the admixture production enterprises, which do not cause pollution in the production process, no adverse effects on the natural environment. And by adding superplasticizer can increase the amount of slag powder or fly ash replacement for cement, ready-mixed mortar admixture Tancheng, not only reduces the cost of production of concrete, ready-mixed mortar admixture Mengyin conducive improve the performance of concrete, and increase the level of green concrete. High performance concrete mix design philosophy is based on performance design as the goal, strength only as a basis for design evaluation. For different environmental conditions, different raw materials, preferred polycarboxylate superplasticizer and high quality mineral admixtures, Yinan ready-mixed mortar admixtures, concrete realization of high performance. Currently, ready-mixed mortar admixtures, common in all kinds of engineering concrete has durability, performance, mechanical properties, economy and other aspects of the requirements to concrete performance goals designed to achieve these requirements well. The durability of concrete can be designed, including volume stability, resistance to chloride ion permeability, frost resistance, alkali aggregate reaction, anti-carbonation, sulphate resistance and other properties of the design; performance design of concrete, including consistency, plasticity easy modification, filling ability, pumpability (such as distance horizontal, vertical pumping performance), stability (anti Bleeding and segregation resistance) and other properties of the design; design the mechanical properties of concrete, including the axial compressive design performance of strength, flexural strength, tensile strength, shear strength, fatigue strength. Juxian mixed mortar admixtures, high-strength construction materials (online consultation), ready-mixed mortar admixture by Linyi City Building Material Co., high-strength. Linyi high-strength building materials Limited (www.lygqjc.cn) Shandong Linyi, concrete and related products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the high-strength building materials led the staff warmly welcome all inquiries negotiations to create a better future for high-strength building materials.
