Soil Stabilization by Using Fly Ash

Abstract: Soil is the basic foundation for any civil engineering structures. It is required to bear the loads without failure. In some places, soil may be weak which cannot resist the upcoming loads. In such cases, soil stabilization is needed. Numerous methods are available in the literature for soil stabilization, but sometimes, some of the methods like chemical stabilization; fly ash stabilization, lime stabilization, cement stabilization etc. adversely affects the chemical composition of the soil. In this study, fly ash mixes with black clay soil to investigate the relative strength gain in terms of unconfined compression, bearing capacity and compaction. The effect of fly ash on the geotechnical characteristics of clay-fly ash was investigated by conducting standard Proctor compaction tests, Atterberg limit, Specific Gravity Test, CBR tests and. The tests were performed as per Indian Standard specifications.
