The main production of high performance concrete water reducing agent, with high water reduction rate, high early strength, low slump loss in time, low bleed air, low shrinkage ratio, high durability and other excellent properties. Its water reduction rate is higher than the previous naphthalene series, sulfamic acid series, fat and melamine series and other high efficiency water reducing agents. Compared with the current market polycarboxylic acid high efficiency water reducing agent, due to the introduction of slump monomer, defoaming functional monomer and alkyl polyether side chain, it has better slump retention and low entraining and low shrinkage ratio. The products are used to prepare low water-binder ratio, high strength, ultra-high strength, high flow and high performance concrete, which provides technical support for the development of domestic high performance concrete. The product is a liquid substance with certain viscosity, non-toxic, pollution-free, belonging to the green type of chemical building materials.
The development of additives in China started later than abroad, but it developed rapidly. In the 1950s, research and application of lignosulfonate and air entraining agents began; After the 1970s, there were independently developed products such as naphthalene based high-efficiency water reducing agents and onion based high-efficiency water reducing agents; In the late 1990s, modified melamine, amino sulfonates, and aliphatic high-efficiency water reducing agents developed rapidly; Since 2006, driven by the construction of high-speed railways, polycarboxylate based high-performance water reducing agents have also experienced rapid development. Water reducing agents have promoted the development of new concrete technologies in China and the application of industrial by-products in cementitious material systems, gradually becoming an essential material for high-quality concrete.
