INFLUENCE OF TILE WASTE POWDER ON THE STRENGTH AND SWELL CHARACTERISTICS OF EXPANSIVE SOIL

Soil stabilization is one of the ground improvement methods of treating the weak soils. unfit for engineering purposes and makes them suitable for construction purposes. This paper focuses on the importance of stabilization of soil using tiles waste as admixture. The expansive soil has serious threat as it possess seasonal variations of moisture content. It leads to severe damages to pavements and foundations of structure. In order to minimize this problem, it needs to be stabilized. The tiles waste has the characteristic to control the swelling behavior of expansive soil because of its high lime content. In this investigation, the geotechnical properties of the soil was determined and the strength characteristics of the soil sample treated with tiles waste powder was observed by varying percentage of Tile waste powder from 0 to 25% at an increment of 5% is mixed with soil sample and tested at different curing periods (1,7,14,28 days). From the analysis of test results it can be observed that the Unconfined Compressive Strength (UCS) and California Bearing Ratio CBR) were improved with an increase in percentage of the admixture and maximum strength was obtained at 20% of tiles waste. In order to reduce disposal problem, tile waste can be effectively used in stabilization works.
