Our Rice Husk Hull Ash (RHA) Specifications:

a. Rice Husk Ash – Premium High Silica Grade

This RHA variant contains

• maximum 1% carbon
• minimum 94% SiO₂ (silicon dioxide)
• maximum 5% moisture

Engineered for demanding industrial applications. Its ultra-high silica and low carbon content make it ideal for high-performance cement blends, refractories, insulation, and specialty ceramics.

b. Rice Husk Ash – High Silica Grade

This RHA variant contains

• 5–10% carbon
• minimum 88% SiO₂ (silicon dioxide)
• maximum 5% moisture

Making it ideal for applications requiring high silica content. Its fine, consistent ash supports use in cement, concrete, refractory, and insulation materials where purity and performance are key.

c. Rice Husk Ash – Standard Grade

This RHA variant contains

• around 10% carbon
• minimum 80% SiO₂ (silicon dioxide)
• maximum 5% moisture

A cost-effective choice suitable for general applications. While lower in silica, this grade remains useful for non-critical construction needs and soil treatment.
