Evaluation of Engineering Behaviour of Expansive Soil with Addition of Lime and Quarry Dust

Abstract

The Kota city, which is situated in Rajasthan state of India, is having a major problem of disposing the quarry dust. Quarry dust is a waste product produced by the stone industry during the cutting and crushing of stone. This byproduct is affecting the environment and land fertility as well. One of the innovative techniques for ground improvement can be practiced by using quarry dust as soil stabilizing agent. This technique may simultaneously offer the environmental sustainability, use of industrial waste, and space saving. The Expansive Soil (ES) deposits in Kota district and its neighboring districts, Jhalawar and Baran, make it difficult to build large constructions. In order to make the soil suitable for construction, quarry dust and lime are used for stabilization of the ES in this study. The UCS and CBR value was increased after adding of quarry dust with 6% lime and stabilized soil has superior load bearing capacity.
