Properties of aggregate and their behaviour in concrete Utilization of Stone Dust as Fine Aggregate Replacement in
Aggregates actually make up 60 to 80 of the volume of hardened concrete So their properties and characteristics are very important Most commonly used aggregates in concrete are sand gravel crushed stone crushed slag and pumice The discussion about both fine and coarse aggregates are given below Fine Aggregates The fine aggregate in carried out to study the suitability and potential use of stone dust as partial replacement of fine aggregate in concrete To accomplish this specimen were cast for different replacement level at an interval of 10 percent to determine workability and compressive strength of concrete at different level of fine aggregate with stone dust
