Abstract
Coal-based thermal power plants are India's primary source of electricity generation, accounting for 59 percent of all electricity generated. The ash concentration of Indian coal is found to be high, ranging from 30% to 50%. The amount of Fly Ash produced is determined by the coal quality utilized and the thermal power plant's operating conditions. The yearly production of Fly Ash in India is currently over 115 million tons. Such a large quantity poses difficult issues in terms of land utilization, health risks, and environmental pollution. Both in terms of disposal and use, extreme caution must be exercised to protect human life, wildlife, and the environment. Fly ash is divided into two categories: Class C and Class F. 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 lime, 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. It is recommended to strengthen and improve various qualities of fly ash by stabilizing it with a suitable stabilizer such as lime in order to popularize its use as a dominant construction material. The goal of this study is to determine the effectiveness of adding lime as a stabilizing agent to waste products like fly ash, as well as its acceptability for use as a building material for structural fills and embankment materials. The above-mentioned geo-engineering features of fly ash, as well as the treated fly ash with various proportions of lime, will be evaluated in this study. There were two parts to the total testing were used to investigate the physical, chemical, and engineer
