Punjab Govt: Ensure 100 per cent utilization of fly ash

Source: The Pioneer, Date: , 2014

In an attempt to contribute to the ‘Fly Ash Mission’, initiated by the Centre’s Department of Science and Technology, the Punjab Government has issued strict instructions to all agencies in the construction sector to ensure 100 per cent utilization of fly ash. For the purpose, the Government has also constituted a high-level committee to ensure strict compliance of instructions. Fly ash is fused residue of clay minerals present in coal. The high temperature generated when coal burns in thermal power plants, transforms the clay minerals in coal powder into a variety of fused fine particles of mainly aluminum silicate composition.  Its utilization, especially in concrete, has significant benefits like it helps in increasing life of concrete roads and structures by improving concrete durability, besides net reduction in energy use and greenhouse gas and other adverse air emissions when fly ash is used to replace or displace manufactured cement. In addition, the fly ash utilization also helps in reduction in amount of coal combustion products that must be disposed in landfills, and conservation of other natural resources and materials.
