A Review of Stabilization of Black Cotton Soil by Industrial Waste Materials

Abstract

In the world, various types of soils are available and found. The soil may be majorly classified in two groups as cohesive soil and cohesionless soil. The classification of soil may be executed as per particle size distribution and consistency limits. The expansive soil having expansion and shrinkage properties which is major issue for geotechnical engineers. Due to swell and shrink properties, the expansive soils change their volume. The black cotton soil is good example of expansive soils. In other hand, million tons of waste material is producing by industries in a year. This is also major issue that “How to utilize industrial waste materials”. These materials are Kota stone slurry, fly ash, marble dust, brick dust, marble slurry etc. In this research paper, reviews are made on discussion and conclusions of experimental study of utilization of industrial waste material to stabilize black cotton soil (BCS). The BCS is stabilized by Kota stone slurry at 5% variation from 5% to 30%, pond ash (from Kota Thermal Power Station) at 10% variation from 10% to 50%, sugarcane bagasse ash at 2.5% variation from 2.5% to 12.5%. The Atterberg’s limit, proctor test, free swell index and CBR test were performed to study the behavior of soil. From test results, it is observed that California bearing value (CBR) is directly proportional to percentage of industrial waste materials.
