Concrete is a heterogeneous mixture of cement, aggregate and water. The construction industry calls for advanced design for executing turnkey projects. So, concrete should have high strength and good workability to meet the requirements for such projects. The demand for natural fine aggregate is significantly increased due to rapid development in construction activities. In the present investigation, Flexural Behavior of Glass Fiber Reinforced Concrete beam for M25 and M50 grades of concrete are studied. Manufactured sand is used as Fine Aggregate. E-Glass Fiber in varying proportions of 0%, 0.1% and 0.2% by volume of concrete is added. Strength properties such as Compressive strength, Split Tensile, Modulus of Elasticity are determined. Flexural Behavior of GFRC Beam specimens and Conventional Concrete Beam specimens are compared. The first crack load, ultimate load, load versus deflection characteristics, ductility factor and stiffness factor of beams are studied. The analysis part is carried out using ANSYS software. The experimental and analytical results are compared and it was observed that increase in percentage of fiber content to certain extent significantly enhance the strength characteristics, ductility and also reduces the propagation of crack width.
