Rice husk ash is a by-product of agriculture generated in rice mills. Rice husk (rice hull) is the coating of seeds or grains of rice. This coating protects the seed or grain during the growing season. The husk converts to hard materials, including opaline silica and lignin. Rice husk contains high amounts of silica (SiO2) when properly burnt.
Hence it can be used as a supplementary cementitious material in combination with cement to make concrete products. When paddy is milled, 80% of the weight is rice and 20% of the weight obtained is a husk. This husk can also be used as a fuel for steam or power generation and other purposes.
