Abstract

Soil stabilization is a method used to increasing the soil mass stability and chemical modification of soils to improve their engineering properties. Stone column method is extremely used to lessen the time taken for prime consolidation. The objective of the study is to improve the soil strength by partially replacing of waste plastic and to compare its efficiency with ordinary stone column. Ground improvement technique by means of stone column is adopted in the clayey soil and to check the compatibility with other techniques. In the above stone column technique, by varying the percentage of plastic waste material by in part replace the aggregates and analyze the load versus settlement behavior of clay soil. The load taken by the clay soil property is improved by replacing waste plastic material by aggregate column. The utmost load taken for 25 mm is to be calculated. The engineering properties like (ϒd max) and (qu) of plastic waste replacement must always be on the higher side. Waste plastic is used for replacing the aggregates column and to decrease the plasticity index. Hence a comparative study is made to calculate the efficiency of plastic waste aggregate column technique with conventional method of improving ground.
