Abstract
This paper investigates the effect of fly ash (generated from thermal power plant, Panki, Kanpur) on geotechnical properties of local soil, Bhauti Kanpur (U.P), INDIA. The fly ash used in the experimental work was of Class ‘F’ and soil was clayey in nature .Fly ash collected from the hopper attached to an electrostatic precipitator when coal was changed at a coal fired power plant. Concerning the major challenges regarding the safe reuse, management and disposal of these wastes an attempt has been made to mix fly ash at 5,10, 15, 20, 25, and 30% on the basis of dry weight with local clay soil. To understand the behavior of fly ash with soil, numbers of laboratory experiments were performed on the local soil (clay) and contaminated soil with varying percentage of fly ash. As the result, it is shown that all the investigated properties were decreased except CBR value and optimum moisture content.
Highlights
Any country's economic & industrial growth depends on the availability of power
Indian coal is having low calorific value (3000-3500 K cal.) & very high ash content (3045%) resulting in huge quantity of ash is generated in the coal based thermal power stations. fly ash is under the manufacturing hazardous waste category
In India, there is reported 7.2 million tone hazardous waste generation from more than 40,000 registered industries according to Controller and Auditor General’s report (CAG-2012)[1] and there is no estimate of unregistered hazardous waste generating industries
Summary
In India coal is a major source of fuel for power generation. About 60% power is produced using coal as fuel. Indian coal is having low calorific value (3000-3500 K cal.) & very high ash content (3045%) resulting in huge quantity of ash is generated in the coal based thermal power stations. In India, there is reported 7.2 million tone hazardous waste generation from more than 40,000 registered industries according to Controller and Auditor General’s report (CAG-2012)[1] and there is no estimate of unregistered hazardous waste generating industries. This industrial hazardous waste has recyclable, landfill able and incinerable components
