Shanghai Hongyun New Construction Materials Co., Ltd. is a domestic private joint venture founded in December 2009, with a registered capital of 51 million yuan, mainly engaged in technology development, technical consulting, technical services in the field of new building materials, production, processing and sales of cement additives, concrete admixtures, accelerators, and sales of building materials.

Our company is located in No. 4768, Jinshan Avenue, the Second Industrial Zone, Jinshan District, Shanghai, with an annual output of 100, 000 tons of high-performance concrete water-reducing agent production base. 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.
