Subgrade Soil Stablization Using Lime and Waste Paper Sludge

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 oncoming 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; lime stabilization etc. adversely affects the chemical composition of the soil. In this study lime and waste paper sludge were mixed with clay soil to investigate the relative strength gain in terms of unconfined compression, swelling capacity and compaction. The effect of these chemicals on geotechnical characteristics of soil is investigated by Proctor compaction tests, unconfined compression tests, swelling test. The tests were performed as per Indian Standard specifications. The following materials will be used for preparing the samples:  Clayey soil  Lime  Waste paper sludge Lime and waste paper sludge was added in varying percentages and that fraction for which maximum strength is obtained were found out.
