An attempt was made to acquire low-cost
construction materials using natural fibres in this research work. Fibers are
generally used in concrete because of both plastic shrinkage and drying
shrinkage and bridge across the cracks that form in concrete to regulate
cracking. In this work, hemp fibres have been used to harness the tremendous
potential of renewable resources in the non-food areas of natural fibres. The
fibres used were 0.25 percent, 0.5 percent, 0.75 percent and 1 percent fibres
in volumetric ratios. The optimal percentage of Hemp fibre in concrete that is
found to result in a substantial improvement in the mechanical properties of
concrete has been tried to ascertain. Grade M25 reinforced concrete beams have
been cast under two-point loading and checked. For RC beams with hemp fibres,
the test results were found to be appreciable. The load capacity of hemp fibre
reinforced concrete beams has been found to be increased by an increase in the
proportion of hemp fibres. An increase of 25% in beam load capacity with 0.5%
hemp fibres was observed. Thus, these natural hemp fibre non-food areas can be
used effectively in the construction of cost-effective structures.
