Polycarboxylate high-performance water-reducing agent is a new generation of water-reducing agent with artificially designed molecular structure. Compared with other water-reducing agents, it not only has a higher water-reducing rate, good slump retention, and a smaller dosage. Because polycarboxylic acid water reducer has high technical advantages, it is the representative variety of new water reducer in the world, it is the common water reducer represented by wood calcium and the high-efficiency water reducer represented by naphthalene series. A new generation of water reducing agent developed after the agent.

Low dosage, high water reduction rate (up to 45%), can be used to prepare high-strength, high-performance concrete.

The loss is small when the slump is light: The slump loss of ready-mixed concrete is less than 15% in 2 hours, which is extremely beneficial for the long-distance transportation and pumping construction of commercial concrete. Good workability of concrete: Even in the case of high slump, the concrete prepared with polycarboxylic acid-based high-performance water-reducing agent will not have obvious segregation and bleeding, and the appearance of the concrete will be uniform in color.

It is extremely beneficial for the preparation of high-fluidity concrete, self-leveling concrete, self-compacting concrete, and fair-faced concrete. When used in the preparation of high-grade concrete, the concrete has good workability, good cohesion, and the concrete is easy to mix. Good compatibility with different types of cement and admixtures. Small shrinkage of concrete: It can significantly reduce the shrinkage of concrete, and significantly improve the volume stability and durability of concrete. Very low alkali content: alkali content ≤0.2%. Good product stability: no precipitation at low temperature. The product is green and environmentally friendly: the product is non-toxic and harmless, and is a green and environmentally friendly product, which is conducive to sustainable development.
