EFFECT OF REPLACING SHARP SAND WITH STONE DUST AS FINE AGGREGATE IN CONCRETE
Keywords:Stone, Dust, Concrete, River, Slump
Concrete is very variable material, having a wide range of strengths and stress-strain curve. Concrete composite material whose basic properties are related to the characteristic of constituent element, especially the aggregate. This research aimed to investigate the effect of replacing sharp sand with stone dust as an alternative to only river sand. Sieve analysis was carried out on the aggregate to determine the size of particle distribution. Slump test was carried out to compare the batches of concrete for the grade, water content between batches of concrete and amount of aggregate. Compressive strength test was carried out on concrete cubes made from sharp sand and concrete cubes made from replacement of sharp sand with stone dust also concrete made from ordinary stone dust at constant of free water/cement ratio 0.5. To check the properties of concrete produced with different materials, the tests were done for 7, 14, 21 and 28 days. The result obtained indicated that the strength of using sharp sand with stone dust in concrete production was higher than the strength of stone dust in concrete also higher than the strength of using sharp sand in concrete.
