Concrete is a tension-weak building material, which is often crack ridden connected to plastic and hardened states, drying shrinkage, and the like. More over, concrete suffers from low tensile strength, limited ductility and little resistance to cracking. The abundant production of fly ash from coal based thermal power plants as waste products becoming problem for their disposal and it is also hazardous to the environment. The inclusion of fly ash in glass fibre reinforced concrete reduces the environmental pollution and improves the workability and durability properties of concrete. In the present experimental investigation glass fibres in different volume fractions with 25% and 40% replacement of cement by fly ash has been used to study the effect on compressive strength, split tensile strength, flexural strength of concrete. For each mix standard sizes of cubes, cylinders and prisms as per Indian Standards were cast and tested for compressive strength, split tensile strength and flexural strength at age of 7days,28 days and 56 days as per Indian Standards.
