In many concrete projects, traditional high-efficiency concrete such as naphthalene is less and less able to meet engineering needs due to the ls of technical performance. A new generation of water reducing agent and polycarboxylate high performance water reducing agent that has attracted much attention at home and abroad. Because it has designed an effective molecular structure based on the mechanism of dispersed cement, it has a super-dispersion type and can prevent concrete slump loss. It does not cause obvious retardation, exerts high plasticizing effect under low dosage, has good fluidity retention, has large freedom of cement to adapt to wide molecular structure, has a large amount of synthetic technology, and has high room for high performance. The effect is remarkable, which can reduce the shrinkage of concrete and the technical properties of extremely low harmful substances, which gives the concrete excellent workability, good strength development, excellent durability, and good performance of polycarboxylate high-performance water reducer. Comprehensive technical performance advantages and environmental protection features meet the needs of modern concrete engineering. Therefore, polycarboxylate superplasticizers are becoming the preferred admixture for the preparation of high performance concrete. According to reports, the use of polycarboxylate admixtures in Japan has accounted for more than 80% of all high-performance admixture products, and North America and Europe account for more than 50%. In China, polycarboxylate superplasticizers have been successfully applied to large-scale water conservancy, bridges, nuclear power and railway projects in the Three Gorges Dam, Sutong Bridge, Tianwan Nuclear Power Plant, Beijing-Shanghai High-speed Railway, etc., and have achieved remarkable results. Besides, the price of polycarboxylate ether price keeps increasing on July ,because on Aug and Oct ,it is the hot season for the polymer concrete application in the market.
