About 30% of the ceramic production all over the world considered as waste. This huge amount of ceramic waste can be recycled in the construction industry, especially in concrete mix design, which is the main scope of this research. Ceramic wastes could provide many advantages rather than sustainability. It is considered economical and can replace cement, coarse aggregate, and fine aggregate, such as sand. In this study, several concrete mixtures were designed according to the ACI standards to assess the ceramic waste concrete for fresh and hardened properties in terms of slump, concrete compressive, splitting tensile and flexural strengths. Six mixes included with 0%, 10%, 20%, 30%, 40% and 50% replacement of coarse aggregate by crushed ceramic waste. By comparing the results between ceramic waste concrete and conventional concrete specimens, the optimum mix design was found to be at 30%-coarse aggregate replacement. Scanning electron microscope tests performed on the concrete specimens to examine the bond between the particles, the porosity, and the elementary composition of the specimens. The percentage of savings in cost estimated when using the optimum mix design (30% coarse aggregate replacement) was about a 30% reduction in the construction cost per the Egyptian market.
