All over the world, Coal based Thermal Power Plants (TPPs) produce huge quantity of ashes as a solid waste which create environmental problems and occupy very large valuable land areas which can be used otherwise. This review paper covers the physico-chemical properties of F class pond ash and their engineering properties like Maximum Dry Density (MDD), Optimum Moisture Content (OMC), California Bearing Ratio (CBR), Unconfined Compressive Strength (UCS), cyclic triaxial and liquefaction, durability, and leaching in alone or with different admixtures. Improved engineering properties of pond ash, make it useful material for road/highway construction. Effective utilization of pond ash in highway construction will not only reduce the problem of ash disposal with a sustainable solution and also ease out the pressure on natural resources. Efforts have been made, to collect available information, to compile and present them in such a manner that these are useful for the field engineers and researchers working in the area. Compiled review shall also be useful for future research in the direction. |
