Addition of smaller size aggregate (12.5mm down size) increases the bulk density. However a stage is reached when the bulk density of coarse aggregate.
The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as “kilograms per cubic metre”. * The bulk density.
The values of bulk density of the coarse aggregates (20mm and 12.5mm size) were first determined separately. The coarse aggregate 20mm and 12.5mm were.
