1995 Japan after polycarboxylate superplasticizer use amounted to 80% of the amount of reducing agent, Qingdao-acid liquor, 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, Kien Keat polycarboxylate liquor, on superplasticizer developed more than 100 US patents have been. These studies compared more concerned with domestic research mechanism, superplasticizer on cement hydration and paste microstructure, poly-carboxylic acid liquor, as well as water-reducing properties of fresh concrete and slump retention performance, concrete entraining, segregation bleeding, coagulation and pumpable some overall performance. Since the late 1990s, the country's research institutes, universities, the strength of the admixture producers through extensive research and many other units in the polycarboxylic acid based high performance water-reducing Jing aspect technetium take a lot of scientific research where China Academy of Building Research, Shanghai Institute of Building Sciences, and other units have independent intellectual property rights of research results have been achieved in industrial scale production, product performance is not inferior to foreign products, it has been successfully used in a number of important projects in the country . However, polylactic acid liquor manufacturers, domestic polycarboxylate superplasticizer product volume and production with completely independent intellectual property rights are still small. Domestic polycarboxylate superplasticizer market share compared to foreign products, there is a large gap, so the performance of polycarboxylate based superplasticizer suppliers in the development and industrial production and engineering in general is still in The initial stages of looking into the future, long way to go _ polycarboxylate liquor production of high-strength building materials (online consultation) _ polylactic acid liquor 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.
