Ceramic tile waste (CTW) stabilized soil had slowly emerged as a sustainable soil stabilization technique. Previous researchers found that different sizes of CTW provided different degrees of performance on different types of soil (e.g., sandy soils, clayey soils). The majority of the research focused on the effect of CTW on compaction properties, Atterberg limits, California Bearing Ratio, and unconfined compressive strength of the soil. However, a limited study was done in examining the CTW effect on tropical residual soil through the consolidated undrained triaxial test. This study aims to investigate the potential application of ceramic tile dust on tropical residual soil from Sg Long, Selangor, Malaysia. Compaction and consolidated undrained triaxial tests were conducted on untreated and ceramic tile dust-treated soil (i.e., 10, 20, 30% CTW) to investigate the effect of CTW on the compaction, isotropic consolidation, and undrained shearing behaviors of the tropical residual soil. From the compaction test, it was found that CTW increased the maximum dry density of tropical residual soil with a slight reduction in the optimum moisture content. From the consolidated undrained test, it was found that CTW delayed the starting time for primary consolidation in isotropic consolidation and increased the undrained shear strength of tropical residual soil. Under the effective confining pressure of 100 kPa, the deviator stress at failure (i.e., at an axial strain of 15 %) for tropical residual soil under undrained shearing was increased by 1.7 times with the addition of 30 % CTW. In conclusion, CTW has the potential to stabilize the tropical residual soil as it can improve the compaction, isotropic consolidation and undrained shearing strength behaviours of the tropical residual soil.
