Silicon Powder can fill the pores between cement particles, generate gel with hydration products, and react with the alkaline material to generate gel. Mixing an appropriate amount of Ultrafine Silicon Powder into cement-based concrete, mortar and refractory castables can play the following roles:

1. Significantly improve the compression resistance, bending resistance, impermeability, anti-corrosion, impact resistance and wear resistance.
2. It has the function of retaining water, preventing segregation and bleeding, and greatly reducing the concrete pumping resistance.
silicon metal powder 325mesh
3. silicon metal powder is amorphous spherical particles, which can improve the rheological properties of concrete.
4. The average particle size of si metal powder is relatively small and has a good filling effect. It can fill in the gaps between cement particles to improve the strength and durability of concrete.
