EXPERIMENTAL STUDY ON HUMAN HAIR FIBER REINFORCED CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT BY GGBFS

One of the most advanced inventions in terms of new materials being employed in concrete has been the development of Fiber reinforced concrete which proves to be a solution for problems relating to the formation of micro cracks. Concrete acquires poor tensile properties which must be rectified by adopting certain alternative measures. One such alternate measure could be the usage of human hair as a fiber reinforcement material since it is better in tension. Hair fiber (HF) is a widely available material which is also economical. It remains non-biodegradable and thereby creates environmental problems, hence it can be used in concrete. Another material that can be used as a replacement material for cement is the Ground Granulated Blast Furnace Slag (GGBFS) which is the waste product obtained during steel manufacturing. It enhances the concrete quality and also minimizes the quantity of cement utilized. This paper details the influence of human hair and GGBFS on the mechanical properties of the reinforced cement concrete and thereby reducing environmental problem by proper utilization. In this investigation, M30 grade concrete was used and the tests were performed on concrete (cubes and cylinder) with and without addition of human hair fiber as 0%, 0.5%, 1%, 1.5%, 2%, 2.5%, and 3% by the weight of concrete.
