At present, the use of waste materials in concrete is an efficient way of managing the nondegradable wastes. Also, the increase in demand of aggregates leads to the replacement of aggregates with waste materials. This paper focuses on replacement of fine aggregate and coarse aggregate partially with ceramic waste and crumb rubber. In this study, the fine aggregate in concrete is replaced with crumb rubber of about 0%, 5%, 10% and 15% and the coarse aggregate is replaced with ceramic tile wastes of about 0%, 5%, 10% and 15%. This paper represents a detailed experimental study on the strength of concrete in terms of compression, split tension and flexure at the age of 7, 14 and 28 days. The mechanical properties of the concrete determined shows better strength in comparison with the conventional concrete. The results concluded that the percentage increase of tile increases the strength of concrete whereas the percentage increase of rubber decreases the strength of concrete.
