• Cement contributes through cementitious reactions, whereas brick dust improves particle gradation, enhancing strength. • The gradation improves at 5% BD content and results in higher strength. However, at 20% BD, gradation and strength both decline. Beyond this point, a further increase in BD enhances gradation and strength. • The combined use of cement and BD performs better than individual use due to the dual mechanism of chemical bonding (cement) and physical gradation improvement (BD). • Higher cement percentages (CP) consistently increase UCS due to more pronounced hydration reactions. The findings of this study have practical implications in the field of geotechnical engineering, particularly in ground improvement and stabilization works. The combined use of cement and brick dust can effectively improve subgrade in pavement construction, embankment stabilization, and foundation soil strengthening in low-strength soil regions. Brick dust, a construction waste material, also promotes sustainable and cost-effective soil stabilization practices. References Al - Baidhani, A., Al - Taie, A., & Student, M.
