Rice Husk Ash
Rice Husk Ash is a potential source of amorphous reactive silica with a wide variety of applications in materials science. Most commonly used in the production of Portland cement, it is a green supplementary material suitable for small to large-scale use, including waterproofing and as an admixture to make concrete resistant to chemical penetration.
Available in a wide range of varieties — including KVRHA White Rice Husk Ash, Rice Husk Ash, Black Radex Rice Husk Ash and Silica Fume Cattle Feed Rice Husk Powder — it is highly cost-effective and can be easily purchased in bulk quantities at nominal prices.
Available Varieties
Our Rice Husk Range
Rice Husk Ash (Black/Grey)
High-silica by-product from controlled rice husk combustion, in black and grey grades. Used in steel making as an insulating/tundish covering compound, and in refractories, concrete, and rubber.
Grey Rice Husk Ash
Finely processed grey-grade ash with consistent particle size and high silica purity. Ideal for ladle/tundish covering, thermal insulation, and as a pozzolanic cement additive.
Rice Husk Powder
Fine tan powder milled from natural husks. Eco-friendly filler for cattle feed, building boards, briquettes, and industrial use.
Silica Fume Cattle Feed Rice Husk Powder
Specially graded husk powder for cattle feed, a natural fibre and silica source, processed for purity.
White Rice Husk Ash
High-purity white-grade ash produced through controlled, complete combustion to remove residual carbon. Its bright colour and elevated amorphous silica content make it ideal for high-grade refractories, specialty cement, and applications demanding low impurity levels.
Black Radex Rice Husk Ash
Carbon-rich black-grade ash valued for its superior insulating properties. Engineered as a tundish and ladle covering compound, it minimises heat loss and oxidation in steel making, and also serves as a reliable source of amorphous silica for refractory applications.
