Experimental Studies on Concrete Elements Using Waste Carbon Black as Filler Material

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. In this study attempt was made to investigate the effect of waste carbon black powder addition as filler material in concrete. Study on uniformity, surface hardness, split tensile strength, flexural strength and compressive strength of concrete specimens containing various percentages of carbon black were carried out. The effectiveness of using waste carbon black as filler in cylinders with rebar was also studied. From the experimental results, it can be seen that optimum percentage of 5% to 8% carbon black can be effectively used for enhancement of properties of concrete.
