• ### CIVIL ENGINEERING MATERIAL TESTING BULKING OF FINE

Aug 02 2017 · Since the volume of the saturated sand is the same as that of the dry sand the saturated sand completely offsets the bulking effect. Note down the level of sand say h 2. Subtract the final level h2 from initial level h1 (i.e. h 1-h 2) which shows the bulking of sand under test. Calculate percentage of bulking using formula given below.

• ### What is Bulking of Sand Its Calculation Classification.

This is because moisture in small proportions forms thin films around the sand grains. Fine sands bulk greater than coarse sand.When the moisture content is increased beyond 8-10 percent the bulking of sand effect almost disappears.. In fact sand grains settled in a water tank will have the same volume as dry sand.
