The sustainability, strength and durability of any of the constituent materials of concrete play an important role in studying and determining the effects on the properties of concrete. Pores in concrete seem to be an immense problem ever since the concrete was discovered. The presence of pores can have negative consequences, including the attraction of water which can result in acid intrusion, freezing and thawing damage, reduced resistance to chloride ions, and decreased compressive strength, etc. Less permeability of concrete plays an important role in gaining strength and reducing the corrosion of reinforcement in concrete. In this paper, an examination is conducted on the characteristics of concrete by incorporating quarry dust (Robo sand) as a substitute for natural fine aggregate, along with the utilization of carbon black as a partial replacement material of cement in concrete by using different percentages of both materials. Experiments have been conducted by introducing carbon black in concrete which is a waste of the rubber industry to act as a filler and which imparts the enhanced properties of concrete. In this present experimental study, various properties of concrete have been studied using quarry dust (Robo sand, artificial sand, stone dust) as a replacement for natural fine aggregate and This study investigates the potential of carbon black as a replacement material for cement in concrete, exploring various combinations of both materials at different percentages. Eventually, the experimental investigation conducted between various percentages of mixes and compressive strength, split tensile strength and flexural strength have been evaluated.
