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 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 of clayey soil strength and increasing the resistance to softening by water through bonding of soil particles together by USING ECO SAND . The ecosand is one such an industrial waste product which accounts about 1000 tonnes per day derived from 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 ecosand 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 examine the soil water characteristic curve  in pressure plate test were investigated. OPTIMUM DOSAGE ARRIVED (%)   OVER ALL (GENERAL)both CH & CI soils.
