Sand is one of the essential concrete materials. Density is an important sand factor. Volume is measured in the case of sand by adding the relative density (specific gravity) of the sand times the liquid volume.
Bulk Density of Sand
Sand’s bulk density or unit weight is the mass or weight of the sand that required a specified unit volume container to be filled.
Bulk Density of sand = (Mass of sand/volume)
Features
- So, if the volume is unit, Bulk Density= Mass.
- Kg / m3 or lb / ft3 unit.
- The volume in this definition is that between sand particles contain both the sand and the voids.
- The average bulk sand density widely used in normal-weight concrete is between 1520-1680 kg / m3 (95-105 lb / ft3).
