In this research, experimental work was conducted to validate the efficiency of Ceramic Waste Powder (CWP), Ceramic Fine Aggregate (CFA) and Recycled Coarse Aggregate (RCA) as a replacement for cement, Natural Fine Aggregate (NFA) and Natural Coarse Aggregate (NCA) respectively; and to examine the effect of replacement on mechanical properties, cost and CO2 emissions of concrete mix.. The importance of this study is the utilization of ceramic waste and RCA together in the concrete mix in order to decrease usage of natural resources in production of concrete, and also to reduce carbon emissions from cement production and dependency on landfills for C&D materials. Eight concrete mixes were prepared in this study, and the mechanical properties, shrinkage, cost and CO2 emissions were obtained for each mix. Finally, a benefit index was derived to estimate the validity of the new recycled concrete in terms of the mechanical properties, cost and CO2 emissions together. It was found that a concrete mix with 100% replacement of NCA by RCA, 20% cement replacement by CWP and 20% NFA replacement by CFA was 26% more advantageous than the control mix in terms of being sustainable and economic. This product proved to be a promising mix, 47% of whose conventional concrete components could be replaced by recycled materials.
