Abstract
Thermal power plants are mostly uses for producing power in India. In these power plants are based on coal. Fly ash and pond ash is the byproducts of coal which is produced in very large amount after burning of coal.Fly ash is divided into two categories: Class C and Class F. Even in the absence of lime, Class C fly ash has a high calcium concentration, making it extremely reactive with water. The percentage of lime in Class F ash is lower. The major goal of the research is to see if class F fly ash, which contains as little as 1.4 percent CaO and has been treated with bentonite, can be used as a construction material in various civil engineering sectors. Fly ash is waste product of power plant often hazardous in nature, easily flammable, corrosive, and reactive, and so have negative environmental consequences. Fly ash particles with comparable diameters ranging from 0.5 to 300 microns have the ability to become airborne and contaminate the environment due to their light weight. Fly Ash discharge in the sea, rivers, and ponds, if not adequately handled, can also harm aquatic life. Mosquitoes and bacteria love to breed in slurry disposal lagoons and settling tanks. It can also contaminate underground water resources by containing traces of harmful metals. This study aims to evaluate the usage of coal ash (fly ash and pond ash) as a useful material by combining it with bentonite in various percentages ranging from 3 to 22%. Pond ash and fly ash are both non-plastic and have a low shrinking rate. The plasticity of the combination is expected to increase with the addition of bentonite, and the coal ash is intended to inhibit swelling and shrinking, preventing the creation of cracks. Bentonite in the mixture is predicted to operate as a self-sealing, low permeability hydraulic barrier due to its swelling capabilities. The mixture will be prepared at its optimum moisture content and maximum dry density. laboratory tests will be conduct to obtain various geotechnical parameters such as plasticity, shrinkage, permeability and unconfined compressive strength to determine the viability of coal ash-bentonite mixture as a useful material. It will be ensured that a mixture of bentonite, fly ash, and pond ash with a benton
