Red mud (RM) and cement kiln dust (CKD) are major industrial waste products from aluminum and cement industries and generate disposal complexities. This paper focuses on the factors affecting red mud interfacial strength using binder cement kiln dust (CKD) and polypropylene fiber (PPF). Laboratory tests were conducted to investigate the dry density, bearing capacity, and shear strength of the material. Red mud was mixed with varying CKD and PPF percentages to achieve the optimal mix proposition. The maximum dry density of red mud barely was found at 14 kN/m3 at optimum moisture contents of 23%. The optimal mix proposition was established as 79.5%RM + 20%CKD + 0.5%PPF, which reveals maximum dry density up to 17.3 kN/m3. The percentage increase in CBR values and interfacial shear strength of materials was found significantly high for the optimal mix proposition. The shear strength parameter measured for the optimal mix using the consolidated drained triaxial shear test is found 45 kN/m2 (cohesion (c)) and 43.74° (interfacial friction angle), respectively. Energy dispersive X-ray (EDX) analyzer tests were also performed to study the elemental composition and intermolecular reaction of materials. The EDX image shows that mix contains calcium, aluminum, and silica in the mix proposition. This optimal mix proposition can be used to strengthen subgrade layers of low-cost pavements, structural fill, or backfill material for retaining walls.
