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 by-products, 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, high-performance 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
Applications of rice husk ash
The ash generated can be stored for silica extraction.
The steam generated is utilized in a steam turbine which generates electricity. Electricity generated is consumed for mill requirements.
Any industry that uses rice husk as fuel for cogeneration can benefit from this technology
Some factories used RHA sprinkle to prevent rapid cooling of the iron and steel so uniformly.
Use as an ingredient in the manufacture of high-strength concrete.
