Experimental study on validating the performance of hair fibre reinforced concrete beam under monotonic loading

Abstract

This research work tries to recommend the right use of disposed human hair. Human hair is abundance and time taking degradable fibre obtainable at very low cost and also carries the permissible tensile load. The scope of the work is to examine the performance of hair fibre reinforced concrete beams under monotonic loading. The investigation also validates the strength and performance of the hair fibre reinforced concrete beams is consistent with conventional beams and steel fibre reinforced concrete beams. This work aims at the confident use of hair fibres easily and practically in the construction industry, to be evidence for enhanced properties of concrete. The one such evidence is being discussed in the paper by taking human hair fibres cleaned with acetone. The human hair fibres of all the sizes are added 3% by weight of cement in concrete as strengthening material. The properties akin to compressive strength, split tensile strength, flexural strength, energy absorption capacity, ductility factor and stiffness of the beams are assessed and hair fibre reinforced concrete is found to be on the upbeat side. In comparison to conventional concrete and conventional beam, micro crack formations are reduced by hair fibres in concrete, and cost-effective to steel fibre reinforced concrete.
