Mineral powder action
1, saving 30-60% cement consumption (including cement mortar) and reducing the engineering cost of cement and concrete.
2. It has the function of pozzolan and improves the compressive strength, tensile strength, bending strength and shear strength of concrete.
3, significantly reduce the hydration heat of concrete, improve the workability of concrete, reduce segregation and bleeding, reduce the temperature difference change and internal stress of mass concrete, and inhibit cracks caused by temperature difference.
4. It can inhibit the alkali-aggregate reaction and significantly improve the ability of concrete to resist the alkali-aggregate reaction.
5. It can exist in concrete in the form of micro-aggregate, which can improve the pore structure in concrete, refine and homogenize the pore size, and improve the impermeability, freeze-thaw resistance and durability of concrete.
6, can significantly reduce the bleeding of cement concrete, improve the workability of cement concrete.
7. It can effectively improve the corrosion resistance of cement concrete to seawater and fresh water and resist sulfate corrosion. It is especially suitable for seawater prevention engineering, underground engineering and pavement engineering.
8. Under the condition of constant water consumption, plastic concrete can be prepared to avoid quality problems caused by dense steel bars and poor vibration. Under the same conditions, it can make concrete flow into the mold, reduce the wear of concrete pump body, pipeline and mold, and prolong its service life.
9. Masonry and plastering cement mortar and low-grade cement can be prepared. Under the condition of meeting the strength requirements, it can not only save 30-60% cement, but also improve the construction operability.
10, suitable for producing environmentally compatible cement-based materials and high-performance concrete additives.
