Experimental Study on Behaviour of Carbon Black on Partial Replacement with Cement

Concrete is the essential construction material used for many applications in the construction industry. Though it is used worldwide, it has its ill effects like the presence of pores and micro-cracks. These ill effects lead to acid intrusion and less resistance to atmospheric attack. As a result, its durability and strength get reduced. The current tendency in the world is to find new materials at lower cost which can guarantee better performances during their incorporations in the concrete. Usage of waste materials for construction purpose enhances the traditional methods of construction. The effect of addition of carbon black powder, a waste from rubber industry as a filler material in concrete is investigated. Study on workability and mechanical properties like split tensile strength, flexural strength and compressive strength of concrete specimens containing various percentages of carbon black were carried out. The effect of added carbon black to cement in concrete mix was studied. This was achieved by replacing cement in different concrete mixes containing 5, 10, 15 and 20% of carbon black to cement. Carbon black as a filler enhances the performance of concrete.
