Bulk Density and Void Percentage Test for Aggregates

The cement mixed with fine aggregate to have mortar for plaster and masonry, and with sand and coarse aggregate to give concrete. As I said, earlier density is the material's mass per unit volume. Since we measure mass in kg or lb and volume in litre or cubic meter or cubic feet, hence density is stated in Kg/m 3 or lb/ft 3 .

Bulking of Fine Aggregate. The volume increase of fine Aggregate due to the presence of moisture content is known as bulking. This is due to the fact that moisture causes a film of water around sand particles which results in the increase of volume of sand, for moisture content of about 5 to 8%, this increase of volume may be a much as 20 to 40%, depending upon the grading of sand.
