Geotechnical Performance Of Stabilized Weak Soils Using A Combinations Of Waste Tyre Powder And Kota Stone Powder

Abstract

Weak soils are primarily defined as clayey soils, having the special characteristics that cause them to deflocculating under some circumstances, erode quickly, and be quickly transported away by water flow. Because these soils have the most potential for problems including heave, shifts, cracks, and settlement, there is an increased danger of foundation damage due to this swelling propensity. Such damage to the foundation might have serious problems, including high repair costs. Clayey soil can be stabilized to make it suitable for building, which reduces settlement and increases the soil's bearing capacity [20]. In this study, two different types of admixtures namely tyre waste powder and kota stone powder which can be used for the stabilizing the clayey soils blended with their optimum combination [11-17]. The optimal  combination of  tyre waste powder and kota stone powder can be arrived by the clayey soils by conducting the various geotechnical investigations with different proportions namely 6% ,8 % ,10% ,12% 14% of kota stone powder  and 12 % tyre waste powder. By the research the optimal combination is arrived to 12% of tyre waste powder and 8% of kota stone powder.
