The fine aggregate is one of the important constituent in preparing concrete. Nowadays, fine aggregate is not fond in abundant quantity and so many replacements were done for river sand like crusher sand, M-sand, bottom ash etc. In this study the replacement is done partially for the fine aggregate with bottom ash which is extracted from Mettur Power Plant. The bottom ash and sand proportions is taken as 10:90, 20:80, 30:70, 40:60, 50:50 (M1,M2,M3,M4 and M5 respectively). The basic tests for all material used in concrete preparation were determined. M20 grade of concrete is casted and the test on fresh concrete is determined for conventional and partially replaced concrete. The specimens (beams, cylinders and cubes) were casted and kept under curing for 7 and 28 days from the cured concrete specimen’s hardened concrete test were determined. The strengt h of concrete for ratios 10:90 and 20:80 are having nearly equal strength comparing to normal concrete. Hence ratio 20:80 is advisable by this experimental study.
