Geotechnical Study on Strength, Dispersion, Durability and Hydraulic Properties of Stabilized CH & CI soils with Ecosand

Abstract

The clayey soils are known to pose severe problems in construction activities which may lead to an increase in construction costs. Mitigation measures as well as repeated and costly maintenance works to be done for soils which are having the properties of high swelling, shrinkage and very low shear strength. this study aims at improving clayey soil strength and increasing the resistance to softening by water through bonding of soil particles together by USING ECO SAND. The eco sand is one such industrial waste product that accounts for about 1000 tonnes per day derived from the cement manufacturing industry. The project was conducted with two types of soil samples namely clay of high compressibility (CH) and intermediate compressibility (CI) and which are blended with eco sand of various dosages such as 10%, 20%, 30% 40% & 50% by weight of soil. With this optimum dosage, the strength studies by UCS test, durability studies by conducting wetting drying cycles & hydraulic properties by examining the soil-water characteristic curve in pressure plate test were investigated. OPTIMUM DOSAGE ARRIVED (%)   OVERALL (GENERAL)both CH & CI soils.
