Micro Silica

• Micro Silica is a very fine Pozzolanic Material composed of Amorphous Silica.
• It is a by product in the process of manufacturing of Silicon and Ferro Silicon alloys.
• It can also be produced by densification of burnt Rice Husk.
• Micro Silica (MS) has proven to be an excellent admixture for Portland cement concrete. Addition of Micro Silica (MS) to concrete mix usually results in significant improvement in strength, durability and permeability. Some of the improvements to the concrete properties occur because Micro Silica is a pozzolan. Pozzolans are finely divided silica that combine with free lime (Calcium Hydroxide) to create more calcium Silica Hydrate.
• Micro Silica (MS) can be used in variety of cementitious products such as concrete, grouts and mortars as well as elastomer, polymer, refractory, ceramic and rubber applications.
• Micro Silica is used in concrete to improve its properties. It has been found that Micro Silica improves compressive strength, bond strength and abrasion resistance; reduced permeability; and therefore helps in protecting reinforcing steel from corrosion.
