STABILIZATION OF BLACK COTTON SOIL USING IRON ORE TAILING

Abstract

The Black cotton Soil can be replaced with stronger material in order to improve its stability .Based Indian Council of Agricultural Research (ICAR) the soils of our country are classified as, alluvial soils, black soils, red soils, laterite soils, desert soils, mountain soils, saline and alkaline soils and peaty and marshy soils. Among these soils Black cotton soils are clayey soil having high compressibility and form a major soil group in our country . The characteristics of soil are high shrinkage and swelling properties. This clay soils found mostly in the central, southern and western parts of India. Because of its highly swelling and shrinkage characteristics, construction of roads on the Black cotton soils have become a challenge to the highway engineers. This Black cotton soil becomes very hard when dry, but loses its strength completely when in wet condition. Soil stabilization is a technique introduced many years ago with the main purpose of improving the soil capacity of meeting the requirement of engineering projects. The soil stabilization technique are used to obtain improve the geotechnical properties soil by adding the material such as lime, cement or industrial by-products such as fly ash, geo polymer etc In this project work an attempt is made to improve the engineering properties of Black cotton soil by industrial products such as iron ore tailings. Here we are using IOT as soil stabilizer
