The main role of Ewende micro silica powder in concrete is as follows:
Improve strength
- Micro silica powder can fill the pores in the concrete, making the concrete more dense, thus significantly improving the strength of concrete. Especially in the early strength, the effect is especially obvious.
- React with the hydration products of cement to generate more stable substances, further enhancing the strength of concrete.
Improvement of durability
- Improve the impermeability of concrete. The filling effect of micro silica powder reduces the pore channels in the concrete, reduces the penetration of water and harmful substances, thus improving the impermeability of concrete and prolonging the service life of the concrete structure.
- Enhancement of chemical erosion resistance. Due to the incorporation of micro silica powder to make the concrete more dense, can better resist the erosion of acid, alkali, salt and other chemical substances.
- Improved frost resistance. Dense concrete structure can reduce the damage caused by water infiltration and icing expansion during freeze-thaw cycle.
Cost reduction
- It can reduce the amount of cement to a certain extent. Because of the high activity of microsilica powder, it can partially replace cement without affecting the performance of concrete, thus reducing the production cost of concrete.
