Rice Husk Ash Ground Powder (Micronized)
Amorphous, micronized high-silica RHA — a reactive pozzolanic supplementary cementitious material (SCM) for concrete, cement and refractory, delivered to a consistent, NABL-tested spec.
What is Rice Husk Ash Ground Powder?
Rice Husk Ash Ground Powder is amorphous, high-silica ash milled to a very fine particle size, giving it a large specific surface area and strong pozzolanic reactivity. It is used as a Supplementary Cementitious Material (SCM): it reacts with free lime in cement to form additional C-S-H gel, which increases compressive strength, lowers permeability, and improves the durability and sulphate / chloride resistance of concrete.
Beyond concrete, the micronized powder serves as a silica source for refractories, a reinforcing and extending filler for rubber and polymers, and a raw material in ceramics. As a partial cement replacement it reduces both cost and the carbon footprint of concrete.
As a micronized rice husk ash supplier and pozzolana / SCM supplier in India, we deliver every batch to a consistent, independently NABL-tested spec with reliable bulk supply and full export documentation. Note: this is a finer, construction-grade product, distinct from the coarser steel-grade ash.
