Abstract
Concrete is naturally a brittle material and it can withstand high compression load but fails to withstand the tensile load. In order to improve the tensile strength in concrete, concrete composites are modified by adding steel fibers in volume fraction. However, discontinuous micro cracks are developed in plastic state of concrete. The drawback can be overcome by modifying the fibrous composites in the form of hybrid fibres. In this experimental work, a triangle series of fibres are selected to establish the hybrid fibres through steel fibers, nylon fibre and coir fibre. The total fibre dosage was restricted to 2% by volume and the hybrid fibre combination was developed by replacing one-third of fibre by other one for making high strength concrete. The performance of hybrid fibre reinforced high strength concrete (FRHSC) were analysed by studying the fresh and hardened properties.
