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

The new generation water reducing agent which attracted much attention at home and abroad, high performance water reducing agent polycarboxylate water, because it really designed effective molecular structure based on a distributed cement mechanism, is superdispersed. 

Type and can avoid concrete slump without noticeable delay, as it can provide higher softening effect with low concentration, good flow retention, high degree of cement freedom to adapt to different synthesis techniques molecular weight and high space shrinkage. , good strength development, excellent durability and an effective polycyclic acid water reducing agent.

 Arboxylic has good comprehensive technical advantages and environmental protection properties that meet the needs of modern concrete technology. Therefore, polycarboxylate ether superplasticizer high performance water reducing agents are gradually becoming a preferred mixture for the production of high performance concretes. 

According to reports, the use of polycarboxylic acid additives accounted for over 80% of all high performance additive products in Japan and over 50% in North America and Europe. 

In my country, polycarboxylate water reducing agents have only been successfully used in the Three Gorges Dam, Sutong Bridge, Tianwan Nuclear Power Plant, Beijing-Shanghai High-speed Rail and other large national water protection systems, bridges, nuclear energy and railways. projects that produce significant results.
