Flyash is a burnt residue of pulverized coal (bituminous or sub-bituminous) and is siliceous in nature. R&D efforts undertaken during the past few decades have revealed that this material can be gainfully utilized in number of ways in building products manufacturing as well as in civil works with adequate durability, due to its superior Geo-technical, Pozzolanic and Physio-Chemical Properties.
Major areas of fly ash utilization established through continual R&D efforts in the country are Building materials as BRICKS, blocks, tiles, etc. Cement and cementitious binders and Special grade materials such as oil well cement, sulphate resistant cement, insulating and low density building products.
Manufacturing of lightweight Aggregates, Controlled Low Strength Material (CSLM), Ferro-cement, wear resistant ceramics and distemper. Also used in Grouting, Engineered fills for low-lying land spaces for human settlement, use in Road Construction and Construction of ash dykes and embankments.
