Experimental Evaluation of Properties of Expansive Soil Using the Mixture of Waste Materials

Abstract

All structures rest on the ground and hence the properties of the soil will influence how the structure reacts to it. For better stability of structure such as road pavements and building foundations, the supporting soil plays an important role. To overcome the drawbacks of expansive soils, the soil can be stabilized with the mixture of waste materials like ceramic powder (WCP) and marble powder (WMP). Soil stabilization is a process by which we can improve physical properties such as its shear strength, load bearing capacity etc. In this study, it is proposed to stabilize the expansive black cotton soil using the mixture of waste materials like WCP and WMP and to evaluate the basic properties of soil such as liquid limit, plastic limit and shrinkage limit, standard Compaction test, CBR, UCS etc. The partial replacement of WCP & WMP with soil was carried out on different percentage ranging from 5% upto 30% at an interval of 5%.Thereafter a comparison was made between the natural black cotton soil and the admixed soil. From this investigation, the obtained results were satisfactory which recommends the use of proposed admixture for soil stabilization.
