ABSTRACT
The massive amount of construction solid waste creates various problems in all aspects of engineering practices. Ceramic tiles is one of construction materials that has a lot of wastage during production as manufacturing slurry and manufacturing dust. Tiles also have considerable amounts of waste during installation at sites which include hacked tiles for the purpose of renovation, tiles with design errors, and those damaged or cracked tiles during transportation. In the current research, recycled ceramic tiles (RCT) were used to treat the physical and mechanical properties of dredged soft clay. The laboratory experiments include Atterberg limits, compaction, specific gravity, and unconfined compressive strength (UCS) tests. Four different sizes (0.063, 0.15, 0.3, and 1.18 mm) of RCT with four percentages (10, 20, 30, and 40%) were used to examine its effect on the soft clay. Results showed that 1.18 mm RCT is the optimum size of RCT in treating the mechanical properties of the soft clay. Besides, 0.3 mm RCT was found to be the optimum size that improved the index properties of the soft clay. The treatment by using RCT in engineering applications would serve as a low-carbon soil treatment method.
