Why do we use sand replacement?

The sand replacement method is used to determine in-place density. The sand replacement method of determination of in situ density uses a sand-pouring cylinder, cylindrical calibrating container, tray with a central circular hole, and a chisel.

What is the meaning of bulking of sand?

The increase in the volume of sand due to increase in moisture content is known as bulking of sand . A film of water is created around the sand particles which forces the particles to get a side from each other and thus the volume is increased.
