The purpose of this study was to investigate the possibility of using crushed stone dust as fine aggregate partially with different grade of concrete composites. The suitability of crushed stone dust waste as fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. The equivalent mixes were obtained by replacing natural sand by stone dust partially and fully. The test result indicate that crushed stone dust waste can be effectively used to replace natural sand in concrete. In the experimental study, of strength characteristics of concrete using crushed stone dust as fine aggregate it is found that there is increase in compressive strength, flexural strength and tensile strength of concrete. The compressive strength of M25 and M30 grade concrete at 28 days with 100 % sand , with 25 % of sand by stone dust ,with 50% replacement of sand by stone dust ,with 100 % replacement of sand by stone dust, The flexural strength of M25 and M30 grade concrete at 28 days with 100 sand , with 25 % replacement of sand by stone dust, with 50% of replacement by stone dust, and 100% replacement of sand. The split tensile strength of M25and M30 grade concrete at 28 days with 100 % sand is, with 25 % replacement of sand by stone dust by stone dust, with 50 % replacement of sand by stone dust, with 100 % replacement of sand by stone dust.
