Fly ash is available in large quantities in the country as a waste product from a number of thermal power stations and industrial plants using pulverized coal or lignite as fuel for the boilers. Recent investigations on Indian fly ashes have indicated greater scope for their utilization as a construction material. If it is directly disposed to the sea or any other sources, contaminates the ground water and other environmental resources. In the present investigation, fly ash from Udupi Power Corporation Ltd. (Udupi District, Karnataka State) is used as an admixture to i:nprove the index and strength properties of the soil available to manufacture the Mangalore tiles. Mangalore tiles are a type of patent tiles native to the coastal Karnataka, India. These were the only tiles to be recommended for government buildings in India during the British regime. But in recent times the roofing tile industries have been facing problems due to non availability of good soil. The soil available for the manufacture of tiles is deficient in required properties for the manufacture. A laboratory study is carried out to find the engineering properties of the soil and also an attempt is made to study the effect of fly ash stabilization (5% to 25%) on plasticity and strength characteristics of soil. It is found that there is an improvement in the strength behavior of the fly ash treated (7 days curing) soil samples.
