ABSTRACT: Concrete is most widely used construction material in the world. However, it has low tensile strength, low flexural strength, low ductility and low energy absorption. An intrinsic cause of poor tensile behaviour of concrete is its low toughness and the presence of defects. Therefore to improve its strength, toughness and ductility fibres are used in concrete. Fibre reinforced concrete is a composite material consisting of cement based matrix with an ordered or random distribution of fibres. The addition of fibres increases the properties of concrete such as flexural strength, impact strength and shrinkage strength. In this present experimental work of investigation the main objective is to study the flexural strength of concrete using different fibres with same aspect ratio for all the fibres and to study the effect of alternate wetting and drying for 30 cycles on Flexural strength of concrete using different fibres such as steel fibre, glass fibre and Polyproplyene fibre with variation of fibre percentage from 0%, 1%, 1.5% and 2% and comparing their strength with 28 days strength of concrete without alternate wetting and drying. From the experimental investigation it is clearly observed that there is very good enhancement in flexural strength for all combinations of fibres and all percentage variation of fibres.
