Study on Strength Properties of Soil Using Wastes as Stabilizing Material

Abstract

Soil is the basic foundation for any civil engineering structure. 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 stabilization by using plastic waste, brick powder, glass powder etc. adversely affect the composition of the soil the material. In this study, plastic waste, brick powder and glass powder were mixed with soil to investigate the relative strength gain in terms of shear strength. The effect of these materials on the geotechnical characteristics was investigated by conducting Standard Proctor compaction tests and direct shear test. The tests were performed as per Indian Standard specifications. The following materials were used for preparing the samples: i. Soil ii. Plastic iii. Brick powder iv. Glass Powder The soil used for these experiments was brought from a site, Dehlan near Una. The physical properties of the soil were determined as per IS specifications. In this test program, without additives soil was tested to find the optimum moisture content, DST value, UCS, CBR. Materials were added in varying percentages and that fraction for which maximum strength is obtained was found out.
