STABILIZATION OF EXPANSIVE SOILS USING MARBLE POWDER AND GLASS POWDER (MP-GP) COMPOSITE

Abstract

Expansive Soils are the type of soils which changes their volumes when encounter water. This change in volume makes them a problematic soil for engineers. Soil Stabilization is the technique used to tackle such problematic soils by enhancing their engineering properties. This research focuses on three main goals, where the first one is evaluating the engineering properties of expansive soils. The other goal is to find alternatives that can be used in place of cement for soil stabilization and the third goal is to utilize the waste materials in soil stabilization to give a solution that is environment friendly. In this research, waste marble powder and waste glass powder were used for soil stabilization. The research had three main objectives. First one is to perform testing on Nandipur Soil and classify it based on the results of that testing. Second Objective was optimization of marble powder and stabilizing the soil using marble powder. Third and last objective was addition of glass powder to previously marble stabilized soil to enhance its strength. The tests performed in this research were Sieve Analysis, Hydrometer Analysis, Atterberg Limits Test, Shrinkage Limit Test, Standard Proctor Test, UCS Test. These tests were first performed on Local Nandipur soil then on soil with 5%, 7.5% and 10% marble powder and 1.25% and 2.5% glass powder.
