Product features:
1、Increase the porosity of cement,
2、Improve the air permeability and water permeability of cement.
3、By adsorbing free calcium oxide in the cement, it adjusts the pH of the cement, reduces the reaction between the cement and acidic substances in the environment, and improves the durability of the cement.
4、Improve the crack resistance and impermeability of cement, reduce the possibility of cement cracking, and enable cement to maintain its stability even in very harsh construction environments.
