Utilization of fly ash in concrete improves strength. Tenacity and ductility beahviour improves concrete durability properties. Hence, this paper mainly focuses on use of fly ash (FA) and steel fiber in concrete. FA content used was 0%, 10%, 20% and 30% in mass basis, and steel fiber (SF) content was 0%, 0.5%, 1.0% and 2.0% by volume basis. Dynamic Modulus of elasticity (Ed) was determined for fly ash based fiber reinforced concrete using NDT equipment.
