Strength, Durability and Hydraulic Properties of Clay Stabilized with Eco Sand

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. Stabilization process enhances the engineering properties of the clayey soils. The eco sand is one such an industrial waste product which accounts about 1000 tons per day derived from cement manufacturing industry. In this study the clay of high compressibility (CH) is 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 studying the soil water characteristic curve in pressure plate test were investigated. The results showed that the improvement in clayey soils such parameters have been observed in optimum dosage of eco sand with CI soil.
