Bulking Of Fine Aggregate and Laboratory test

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.
