Construction and demolition waste and shortage of natural resources is growing issue that has been arisen through recent years all over the world. Although concrete, the most adaptable construction material, is a key factor in the expansion of the industrial and infrastructural sectors, it has been argued that concrete is not an environmentally friendly material because of its destructive resource-consumption nature and the potential for serious environmental impact after its use. However, it will continue to be the dominant building material utilised on a global scale. The present study aimed to assess the concrete properties with the effect of silica fume and recycled aggregates with the design mix of M30 grade of concrete. The study aimed to investigate the effects of replacing natural coarse aggregates with various percentages of recycled concrete aggregates (10%, 20%, 30%, 40%, and 50%) and using silica fume (2.5% and 5%) as a substitute for cement in the production of concrete. To achieve this, different concrete mixes were prepared and tested for their compressive strength, split tensile strength, and flexural strength, while also conducting a rapid chloride permeability test to determine the chloride ion penetration. The results showed that using recycled aggregates up to 20% can optimize compressive and tensile strength, while flexural strength can be optimized up to 30%. The use of recycled aggregates in concrete production can help reducing the consumption of natural resources and incorporating silica fume as a cement alternative can help reduce the environmental impact of cement production upto5%.
