Abstract
Human hair is considered as a waste material in most parts of the world and is a common constituent found in municipal waste streams which cause enormous environmental problems. This is an attempt to find the possibilities of using hair as fibre reinforcement in concrete, thereby forming an alternative way for the safe management of hair waste. Human hair is strong in tension; hence it can be used as a fibre reinforcement material. Hair Fibre, an alternate non-degradable matter, is available in abundance and at a very cheap cost. Present studies have been undertaken to analyse the effect of human hair on plain cement concrete on the basis of compressive, crushing and flexural strengths and cracking control to economize concrete and to reduce environmental problems. Experiments were conducted on concrete cubes with various percentages of human hair fibre i.e. 0%, 1.5% and 2% by weight of cement. By testing we found that there is an increment in the various properties and strength of concrete by the addition of human hair as fibre reinforcement which makes it suitable for an alternative additive for concrete to enhance its mechanical properties. Also, hair fibre reinforced concrete can be an alternative method for the hair waste management.

Fibre reinforced concrete can offer a convenient, practical and economical method for overcoming micro-cracks and similar type of deficiencies. Since concrete is weak in tension hence some measures 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 cheap cost. It also creates environmental problem for its decompositions. Present studies has been undertaken to study the effect of human hair on plain cement concrete on the basis of its compressive, crushing, flexural strength and cracking control to economise concrete and to reduce 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% and 3% by weight of cement. For each combination of proportions of concrete one beam and three cubes are tested for their mechanical properties. By testing of cubes and beams we found that there is an increment in the various properties and strength of concrete by the addition of human hair as fibre reinforcement.
