Concrete is a brittle material with a low tensile strength. Fibres when added to concrete increases strength, toughness and ductility. The addition of fibres improves the post-cracking behaviour of concrete. In this project, the strength characteristics of hybrid fibre reinforced concrete is studied experimentally by testing cubes, cylinders and prisms under compression, tension and flexure. Fibres used are glass and steel fibres. The combinations of different types of fibres potentially will improve the overall performance of concrete. Admixtures silica fume and fly ash improves workability of concrete. M25 grade concrete was investigated with addition of steel fibres and glass fibres with admixtures silica fume and fly ash. The test results shows that use of hybrid fibre reinforced concrete with admixtures improves compression, split tensile and flexural performance.
