Rice milling industry generates a lot of rice husk during milling of paddy which comes from the fields. This rice husk is mostly used as a fuel in the boilers for processing of paddy. Rice husk is also used as a fuel for power generation. This RHA is a great environment threat causing damage to the land and the surrounding area in which it is dumped. RHA is a carbon neutral green product. Lots of ways are being thought of for disposing them by making commercial use of this RHA. RHA is a good super-pozzolan. This super-pozzolan can be used in a big way 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. Silicon is the second most common element in the Earth's crust, comprising 25.7% of the Earth’s crust by weight. It is shiny, dark gray with a tint of blue. Silicon, atomic number of 14, is a semi-metallic or metalloid, because it has several of the metallic characteristics. Silicon is never found in its natural state, but rather in combination with oxygen as a silicate ion (SiO4) in silica-rich rocks such as obsidian, granite, diorite, and sandstone. Feldspar and quartz are the most significant silicate minerals. Silicon alloys with a variety of metals, including iron, aluminium, copper, nickel, manganese and ferrochromium. Used in manufacture of special steels and cast iron, aluminum alloys, glass and refractory materials, ceramics, abrasives, water filtration, component of hydraulic cements, filler in cosmetics, pharmaceuticals, paper, insecticides, rubber reinforcing agent - especially for high adhesion to textiles, anti-caking agent in foods, flatting agent in paints, thermal insulator. Silicon is used in the aluminium industry to improve castability and weldability. Silicon has a wide range of applications because of their excellent properties of thermal stability etc. They are widely used as from stabilizers for poly methanes, diffusion, pumps antifoaming agents for liquid, textile finishes. Silicones also find application in manufacturing of weather proofing concretes. There is wide scope and good market potential of products manufactured in this sector.
