Fill a sample of moist fine aggregate (sand) into a measuring cylinder in the normal manner. Note down the level, say h1.
Pour water into a measuring cylinder and completely cover the sand with water and shake it. 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 h2.
Subtract the final level h2 from initial level h1 (i.e. h1-h2), which shows the bulking of sand under test.
Calculate percentage of bulking using formula given below.
