Concrete is weak in tension and is often affected by cracking and scaling which are connected to plastic state, drying shrinkage and hardened states. Concrete mainly suffers from limited ductility, low tensile strength, and slightly resistance from cracking. With increase in coal based thermal power projects there is increase in production of fly ash which is a waste material and the disposal of this fly ash is hazardous to environment if it is not disposed well. Glass fibre is obtained from the molten glass of a specific composition which is a chemically inorganic fibre as they are low-cost and ductile behavior without compromising on strength parameters. The substitution of cement with fly ash in concrete leads to environmental degradation and raises the durability and mechanical properties of concrete. Replacement of Cement by Glass fibres in different fractions with 0%, 1%, 1.5%, 2%, 2.5%, 3% and 30% of Fly ash has been used, which satisfies the various structural properties of concrete like compressive strength, flexural strength. Workability was enhanced by the inclusion of super plasticizer in concrete which was adopted up to 0.5% by the weight of cement. As per Indian Standards, standard sizes of cubes and beams were casted and tested for compressive strength, flexural strength at age of 7days, 14 days and 28 days.
