Abstract

A sizeable unit of broken ceramic tiles that were employed as finishing on a construction site are now rubbish and are usually left alone. The goal of this experiment is to replace some of the cement and coarse particles in concrete with recycled ceramic tiles. To replace cement and fine aggregates, respectively, ceramic tiles were ground into powdery and cushed-fine forms and broken into coarse form to replace coarse aggregates in proportions ranging from 0 to 30% at intervals of 5%. For each replacement (0-30%), concrete cubes with a water cement ratio (WC) of 0.4 were cast and allowed to cure for 7, 14, and 28 days, respectively. This investigation, which was conducted in compliance with British Standard, concentrated on the compressive strength of both normal and ceramically treated concrete. In comparison to the control (25.77 Nmm2), the compressive strengths of the modified concrete (5-30%) at 28 days were 14.57mm2, 14.27Nmm2, 13.95Nmm2, 13.56Nmm2, 13.16Nmm2, and 12..96Nmm2, respectively. It may be established that ceramic tiles in powdery and coarse forms, respectively, cannot replace the combined cement and coarse aggregates with the same percentage of substitution.
