In this study, class F fly ash (FA) is used as a partial replacement of fine aggregate on strength enhancement of concrete. Two series of concrete mixes are prepared. In the first series, fine aggregate is replaced with class F FA by weights such as 0, 10, 20, 30, 40 and 50% with varying w/c ratio to meet the required workability. In the second series, fine aggregate is replaced with class F FA by weights such as 10, 20, 30, 40 and 50% with constant w/c ratio (0.375) and the required workability was maintained by mixing the superplasticiser, i.e. Cera Hyperplast XR-W40. The design mix is carried out for M30 grade concrete. The workability of concrete is determined by slump test and hardened concrete properties such as compressive strength, split tensile strength and flexural strength are determined at 7, 28 and 90 days. The test result indicates that the compressive strength of concrete increases up to 30% replacement of fine aggregate with FA whereas for split and flexural strength, it increases up to 40% replacement of fine aggregate with FA.
