Sustainable Utilization of Calcium Carbide Residue along with Polypropylene Fiber Waste Materials for Accessing Swelling and Strength Characteristics of Black Cotton Soil

Abstract

Due to industrialization and modernization, huge amount of waste generated by many industries causes a huge threat to the human health, environment and aqua life due to disposal problems. The present study focuses on utilizing industrial wastes to strengthen geotechnical properties of black cotton soil. The toxic compounds included in calcium carbide residue (CCR) created by the acetylene gas companies and polypropylene fiber made by the textile mills are both highly polluting. These materials can be utilized in soil stabilization alone and in combination in various proportions to obtain the finest subgrade material. The use of such industrial waste for subgrade soil stabilization is a cost-effective way of building pavements. This study examines the effects of addition of different percentages of CCR and fiber contents on Atterberg’s limits, compaction characteristics, unconfined compressive strength and California bearing ratio.
