This study investigated the effects of various percentages of stabilizing materials, specifically Fly Ash Brick Powder (FABP) and Red Brick Powder (RBP), on the behavior of expansive soil. Key findings revealed significant enhancements in soil properties when incorporating these stabilizers at concentrations of 5%, 10%, 15%, and 20%. Notably, the liquid limit decreased substantially, from 53.8% to 48.08% for FABP and from 53.8% to 41.98% for RBP, with the most considerable reduction occurring at the highest replacement level. This decrease is beneficial for soil strength, improving stability, load-bearing capacity, and moisture resilience, thereby making the soil more suitable for construction applications. The plastic limit also declined with increasing stabilizer percentages, falling from 32.71% to 25.93% for RBP and from 32.71% to 28.66% for FABP, with a slight increase at 20% replacement. This reduction enhances soil strength by decreasing plasticity, increasing shear strength, and improving compaction, which collectively contribute to greater stability. The plasticity index exhibited a favorable decrease from 21.09% to 16.36% for FABP and from 21.09% to 16.05% for RBP, indicating enhanced compaction characteristics and reduced deformation potential. Compaction characteristics were reflected in the Maximum Dry Density (MDD), which decreased initially for FABP before increasing at 20% replacement, while RBP showed a steady rise, signifying improved load-bearing capacity and stability. The Optimum Moisture Content (OMC) decreased for both stabilizers, further enhancing compaction and reducing plasticity. The California Bearing Ratio (CBR) also increased significantly, from 4.70% to 5.46% for FABP and from 4.70% to 7.59% for RBP, underscoring RBP's superior performance as a stabilizer. Overall, the investigation concluded that Red Brick Powder was more effective than Fly Ash Brick Powder, demonstrating better performance in Atterberg’s Limits, compaction characteristics, and CBR analysis, ultimately indicating its greater potential for enhancing the stability and durability of expansive soils in construction applications.
