Bulking of Sand in Concrete - Cement and Concrete in India ,Free moisture content in sand causes an increase in its volume; this is known as the Bulking of Sand. Sand enhances the density and workability of concrete and reduces permeability thus helps in increasing the compressive strength of concrete. The presence of silt/clay in the sand should not be more than 7% by volume and not than 3% by weight.
