Advanced Utilization of Industrial Waste Residuals: Red Mud and CKD for Sustainable Pavement (KEY IJP************174)

• Kundan Kumar,Afzal Khan

Abstract

Industrial waste management is a pressing concern globally, and this research explores the potential reuse of Red Mud (a steel industry by-product) and Cement Kiln Dust (CKD, a cement industry waste product) in pavement construction. The study evaluates the geotechnical properties of cohesionless soil mixed with varying proportions of Red Mud and CKD. Experimental investigations, including grain size analysis, permeability, compaction, California Bearing Ratio (CBR), and Direct Shear tests, indicate that the mix containing 70% cohesionless soil, 30% Red Mud, and 25% CKD is optimal for subgrade construction. The research not only offers an innovative solution to waste disposal but also enhances the strength and durability of pavements.Keywords: Red Mud, Cement Kiln Dust (CKD), Cohesionless Soil, Pavement Stabilization, Industrial Waste Utilization, Soil Reinforcement
