A sizeable unit of ceramic tiles that were broken while being employed as finishes on a construction site becomes waste and is mostly left unutilized, however it is occasionally used to tile retail spaces. This experiment attempts to partially replace cement and coarse aggregates in concrete by using recycled ceramic tiles as a replacement material. For the replacement of coarse aggregates and cement, respectively, in amounts ranging from 0 to 30% at intervals of 5%, ceramic tiles were broken into coarse and powdery forms. For each replacement (0-30%), The water cement ratio (W/C) of 0.4 was used to cast concrete cubes., and curing period was 7, 14, 21 and 28 days. This investigation, which followed British Standard, focused on the compressive strength of both normal and ceramically treated concrete. In comparison to control (25.77 N/mm2), the compressive strengths of the modified concrete (5-30%) at 28 days were 22.38N/mm2, 21.38N/mm2, 23.69N/mm2, 19.71N/mm2, 17.51N/mm2, and 14.82N/mm2, respectively. Predictive model showed that flexural and spilt tensile strength fall within the specified range for (2.53 -3.79N/mm2) and (2.02-3.03N/mm2) in accordance with ASTMC78 & C293 for flexural strength and ASTM C496 for spilt tensile strength. It may be inferred that ceramic tiles in powdery and coarse forms, respectively, can replace the combined cement and coarse aggregates up to 15% in concrete, with the resulting concrete possessing qualities equal to conventional concrete
