In many concrete projects, traditional high-performance concretes, such as the naphthalene series, are increasingly unable to meet project needs due to technical performance constraints.

 A new generation water-reducing agent that has attracted a lot of attention at home and abroad, polycarboxylic acid, a high-performance water-reducing agent because it actually designed an efficient molecular structure based on a dispersed cement mechanism, is dispersed in the supertype and can prevent concrete formation. 

Recession loss without causing obvious deceleration, it can have a higher softening effect with low quality, good fluidity retention, high freedom of cement to adapt to many molecular structures, multiple synthesis techniques and large space for high performance, which can improve concrete Impact is significant, it can reduce concrete shrinkage, harmful substances has a very low and other technical performance properties that give the concrete excellent workability, good strength development, excellent durability and high performance polyacid-based water-reducing agent. 

Arboxylic has good technical performance advantages and the environmental protection properties meet the needs of modern concrete technology. Thus, high performance dewatering agents based on polycarboxylic acids are gradually becoming a preferred blend for the production of high performance concretes. 

According to reports, the use of polycarboxylic acid additives accounted for more than 80% of all high-performance additive products in Japan, and more than 50% in North America and Europe. In my country, polycarboxylate water-reducing agents have only been used successfully in the Three Gorges Dam, the Sutong Bridge, the Tianwan Nuclear Power Plant, the Beijing-Shanghai High-Speed Train, and other large national water protection systems, bridges, and nuclear power plants. and rail projects with significant results.
