An increase of bulking in sand effects concrete mix and results in harsh behaviour while placing. Moisture content less than 5% should be preferred for construction purposes. In order to calculate the bulking of sand/ Percentage of moisture content in the sand, the moisture content of sand is further increased by adding some more water.
