Concrete admixture is added in the process of mixing concrete, which accounts for less than 5% of the cement mass, and can significantly improve the performance of concrete. The characteristics of concrete admixtures are many varieties and small amount of admixture, which has a large impact on the performance of concrete. It has the characteristics of less investment, quick effect and significant technical and economic benefits. With the continuous advancement of science and technology, admixtures have been increasingly used, and admixtures have become the fifth important component of concrete in addition to the four basic components.

Admixtures have a certain improvement on the anti-carbonization performance of concrete. There is a certain linear relationship between the carbonation depth and porosity of concrete; admixtures have a great influence on the frost resistance of concrete. Concrete with air-entraining water reducer The performance is better, and the early mixed strength agent alone has no effect on improving the frost resistance of concrete.

The admixture is the fifth component of concrete. The admixture can improve the workability of the concrete and increase the strength and durability of the concrete. The characteristics of concrete admixtures are many varieties and small amounts, which have a great impact on the performance of concrete. Therefore, its variety selection, application technology and quality control are more important than other concrete materials.

Dongke Polycarboxylate Superplaticizer has been widely used in different construction projects,such as High-speed train,Dam,high way…

Without changing the ratio of various raw materials (except cement) and the strength of concrete, the amount of cement can be reduced, and the addition of concrete water reducer with cement quality of 0.2% to 0.5% can save more than 15 to 30% of cement
