SUSTAINABLE SOIL STABILIZATION USING INDUSTRIAL BY-PRODUCTS: FLY ASH, LIME, AND QUARRY DUST

Abstract

Soil stabilization is necessary to improve the strength of weak soils used in construction works. Clayey soils usually have low bearing capacity, high shrink swell behavior, and are sensitive to moisture. In this study, we used industrial waste materials fly ash, lime, and quarry dust are to improve soil properties. The soil samples were replaced and mixed with soil in different percentages of fly ash, lime, and quarry dust and tested and examined as per IS standards. These results have the comparisons of compaction test, Optimum Moisture Content (OMC), and California Bearing Ratio (CBR) tests with respect to original soil. The results showed that the treated soil samples have better strength and load-bearing capacity compare to original one. This mix proportion of mix (fly ash 20%, lime 4% and quarry dust 12%) helps in improving soil performance while stabilizing soil for foundations, and pavement construction and reducing environmental pollution by using these industrial waste materials.
