Experimental Analysis and Application of Human Hair as a Fibre Reinforced In Concrete

Abstract

Fibre-reinforced concrete offers a convenient, practical and economical technique for overcoming micro-cracks. Since concrete is weak in tension hence some procedures must be adopted to overcome this deficiency. Human hair is strong in tension; hence it can be used as a fibre reinforcement material. Hair Fibre (HF) an alternate non-degradable matter is available in abundance and at a very economical cost. It also creates environmental problems for its decomposition. Present studies have been undertaken to study the effect of human hair on plain cement concrete based on its compressive, flexural strength and cracking control to economic concrete and to moderate environmental problems. Experiments were conducted on concrete beams and cubes with various percentages of human hair fibre i.e. 0%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5% by weight of cement. For each grouping proportions of concrete beams and cubes of standard sizes are tested for their mechanical properties at curing periods of 7, 14 and 28 days. By testing cubes and beams, we initiate that there is a rise in the various properties and strengths of concrete by the addition of human hair as fibre corroboration in concrete.
