Microsilica, also known as silica fume, which is a by-product of producing silicon metal or ferro-silicon metal. It is collected from the flue gases from electric arc furnaces. It is a highly reactive pozzolanic powder and it is more important for the concrete industry.
Microsilica is an extremely fine powder and it is commonly used in concrete structures that need a high degree of impermeability or required high-strength in concrete.
Microsilica is now used in more & more projects wherever durability & strength is the prime concern.
Benefits of Microsilica
Increase Concrete Strength
Improve Significantly Concrete Durability
