Increase in the use of concrete in construction industry in Nigeria has led to the rise in the cost of its constituent material. This has necessitated research into the use of alternative material which is cheaper and can produce a comparable level of strength as the conventionally used ones. This paper present the results of an investigation into the compressive strength characteristics of concrete made with ceramic tile waste as coarse aggregates. The percentage of tile waste was varied in steps of 25% from 0 to 100%. For each considered percentage of tile wastes, three (3) set of concrete cubes were cast each for 7, 14 and 28 days curing age which resulted in a total of 45 cubes. The test result indicated that the compressive strength reduces as the percentage of tile wastes increases. The 28th day compressive strength for 25% and 100% replacement were 23.93N/mm2 and 21.43N/mm2 respectively which is adequate for structural light weight concrete. The specific gravity of tile waste was found to be 2.27 which is comparable to the specific gravity of conventional aggregate. Slump test also showed that workability of concrete decreases wth increasing tile waste content.
