Fly ash has emerged as novel engineering materials which lead to global sustainable development and lowest possible environmental impact with considerable promise as binders in the manufacture of concrete. In this paper, the results of laboratory investigation conducted on the structural behavior of reinforced concrete beam with high volume of low calcium (class F) fly ash are presented. Experimental investigation included testing of nine reinforced concrete beams with and without fly ash. Portland cement was replaced with 50% fly ash and Conplast SP430 was used as superplastisizer for the casting of beams. Data presented include the load-deflection characteristics, cracking behavior, ductility indices, moment- curvature and end rotations of the reinforced concrete beams with and without fly ash when tested at 28 days, 56 days and 75 days. The investigation revealed that there is a significant improvement in flexural strength of reinforced fly ash concrete beams beyond 28 days.
