Applications of Rice Husk Ash Silica - A Guide - Bee Chems

Rice husk disposal is a big concern for farmers and millers all over the world. When rice husk is used as a fuel in a boiler, it produces rice husk ash (RHA). RHA is a waste product that comprises 60 to 80 percent amorphous silica (SiO2), which is used in a variety of industries. Rice husk ash, unlike other industrial byproducts, is made from agricultural waste.

Because of the abundance of RHA generated from combustion, it is worthwhile to use the properties of silica developed from RH and RHA. RHA silica can be used to make special concrete mixes. There is a growing demand for fine amorphous silica in the production of special cement and concrete mixes, highperformance concrete, high strength, low permeability concrete, for use in bridges, marine environments, nuclear power plants, etc.

Bee Chems is a popular rice husk ash silica manufacturer that has developed economical, eco-friendly, easy ways of extracting high-purity silica from RH/RHA. Rice husk ash silica are used in steel industries, agro-industries, etc. Adding rice husk silica to concrete mix even in low replacement can dramatically enhance the strength of concrete by 10-20%. RHA silica helps develop excellent water-resistant properties and is used in waterproofing compounds that can reduce water penetration by as much as 60%.

Properties of rice husk ash silica High pozzolanic activity causes the strength and durability of concrete to be enriched A potential green resource A useful technique for waste disposal and utilization

Energy effective Applications of rice husk ash Silica generation: The ash generated can be stored for silica extraction.

Electricity generation: The steam generated is utilized in a steam turbine which generates electricity. Electricity generated is consumed for mill requirements.

Environment-friendly: Any industry that uses rice husk as fuel for cogeneration can benefit from this technology Steel Industry Some factories used RHA sprinkle to prevent rapid cooling of the iron and steel so uniformly.

High strength concrete Use as an ingredient in the manufacture of high-strength concrete.

Benefits of precipitated silica generated from rice husk ash Precipitated silica from rice husk ash is from a bio source and is non-toxic Precipitated silica is extracted from waste hence nullifying the raw material cost Lowers the heat of hydration by as much as 30% Help reduce chloride ion penetration by as much as 50% Promotes a better working condition for those working with concrete Packaging Options 250 Kg. HDPE barrels 1000 Lts. IBC/Tote tanks 20-25 metric tonnes in ISO tankers 20-25 metric tonnes in Flexi tanks The company also provides custom packaging options for special requirements.
