To estimate the extent of bulking of sand a sample of moist fine aggregate is filled into a measuring cylinder. The level of the fine aggregate is noted as 'h1' Now water is poured into the measuring cylinder till the fine aggregate is completely inundated. Since the fine aggregate is completely saturated, there are no bulking effects.

Equally important, a test of density while dry will determine the density of your soil when dry. While sand seems to be quite dense, this dry density test is about voids or open spaces between soil particles. Clay, for example, has very few voids when compared to sand which is generally quite porous. 3. Atterberg Limits.
