EFFECTS OF INCLUSION OF HUMAN HAIR ADDITIVES AND POLYPROPYLENE FIBRE IN CONCRETE

Civil Engineering

Human Hair is an alternative for fiber reinforced polymer which is available in abundance and at a very cheap cost. It also creates environmental problem for it decomposition. Human hair is also non-degradable and on whole, about three to four tons of human hair are found as a waste in India. 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 and polypropylene is strong in tension; hence it can be used as a fibre reinforcement material. By testing we found that there is an increment in the various properties and strength of concrete by the addition of human hair and polypropylene as fibre reinforcement which makes it suitable for an alternative additive for concrete to enhance its mechanical properties. This paper explores and assesses use of human hair in concrete from the perspective of expanding its utilization as a resource as well as convenient, practical and economical method to overcome the micro-cracks and similar types of deficiencies in concrete.
