Human Hair Fibre Reinforced Concrete
Enhance the physical and mechanical properties of concrete are a potential area of research. Fibre reinforced concrete is one among those advancements which offers convenient, practical and economical methods for overcoming micro cracks and similar type of deficiencies. Since the concrete is weak in tension, fibre help to overcome this deficiency. There are several types of fibre which serves this purpose, this paper investigates the suitability of human hair. 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 environmental issue. Hair fibre, an alternate non-degradable matter is available in abundance and at a very cheap cost. This paper compares the strength and durability of ordinary concrete with hair fibre reinforced concrete of M20 grade with 0%, 0.5%, 1% 1.5%, 2% addition of hair by weight of cement. The result shows that addition of human hair fibre enhances the binding properties, micro cracks control, imparts ductility and also increases the spalling resistance. The experimental findings in overall studies would encourage further research in this direction for long term performance to extending this cost effective type of fibres for use in structural application.
