N2 - In order to minimize the environmental impact of carbon-dioxide emission in cement production, a study focusing on development of waste-containing concrete was carried out to create a formulation of cementitious material by introducing Ground Granulated Blast Furnace Slag (GGBS) and recycled aggregates into concrete to replace cement and aggregates respectively. Compressive test was performed for concrete specimens mixed with different proportions of recycled wastes. The results show that by introducing GGBS and recycled aggregates the compressive strength decreased considerably. Concrete containing 70% GGBS and 100% recycled coarse aggregate was considered as the optimum formulation, and the compressive strength reached 74.55% of that of normal concrete. Environmental and economic advantages were assessed for the optimum combination, with only a 6.17% increase in material cost, a 64.84% reduction in carbon-dioxide emission and a 51.80% reduction in energy consumption achieved.
