I believe the test results of some water reducing agent rather than the product manual instructions marvelous product, or even a very good product test results, east polycarboxylate water reducer, for a specific project may not be suitable, but on the contrary, some Although the product is not very outstanding test results, Polycarboxylate production, there may be just an engineering concrete material formulated to meet the requirements. In addition, due to changes in raw materials, test results when tenders are not representative of the actual implementation of the project of. GB50119-2003 "concrete admixture technical specifications" in "2.1.4" clearly states: raw materials used in concrete mixed with additives such as cement, sand, stone, admixtures, additives shall comply with national regulations in force in the relevant standards; When the trial with mixed concrete admixtures, polycarboxylate water reducer sales, raw materials used by the project should be used, Polycarboxylate small materials, test items shall be determined according to the design and construction requirements, the same test conditions and construction conditions, When works with raw materials or concrete performance requirements change, there should be another trial with the test. Domestic manufacturers still only supply comparative single commodity. One of the key factors affecting the function of the structure characteristics of a polycarboxylic acid copolymer, impact research Polycarboxylate the structure of the application performance is a very important discussion content. Influence Oceanpower Engineering Technology Co., Ltd. and State Key Laboratory of joint research on polycarboxylate cement and concrete structure features, prepared a variety of different molecular weights, narrow molecular weight spread contrast, the polymer structure uniform acid polymer developed a good contrast to the cement applicability Polycarboxylate, at a lower dosage has a strong dispersion and high water reduction. Strong polycarboxylate superplasticizer, high-strength construction materials (certified), east Polycarboxylate high-strength building materials provided by the Linyi City Limited. 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.
