Soil stabilization by using municipal solid waste ash

Abstract

This report presents the analysis of soil using municipal waste ash in soil stabilization for different engineering properties. As solid waste disposal being a major environmental problem, because of unavaiblity of lands for disposal. Due to fast growth in construction industry, land is not available as per construction requirements. For dealing with these problems, solid waste can be incinerating to reduce its volume by 80%, and further can be used as soil stabilization material. It enhances the soil properties and also solves the problem of solid waste disposal in city. This work deals with estimation of engineering properties of soil i.e. shear test, maximum dry density vs. optimum moisture content and permeability. Experimental work shows that use of 10% MSW ash by weight of soil can improve the properties at larger extends. The foundation of a building or road is an essential part for effective transmission of load to the subsoil present beneath it. The experimental work is carried out to find the effect of varying proportions of waste materials on shear strength, compaction and permeability of soil. Pursuant to this, following objectives are proposed in the present investigation. 1) To use municipal waste ash as a stabilizing material and to solve the problem of waste disposal. 2) To evaluate the strength characteristics of soil for different proportions of ash in replacement of 5%, 10%, 15% and 20% 3) To study the results of replacement and concentration on future use.
