The specific gravity may be expressed as bulk specific gravity or apparent specific gravity. Bulk specific gravity and absorption are based on a 24 ± 4-h soaking time for the rock specimens tested. This test is appropriate for breakwater stone, armor stone, riprap, and gabion sized rock materials.
Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is the measure of strength or quality of the specific material. Aggregates having low specific gravity are generally weaker than those with higher specific gravity values.
2021-8-26 · Density is an important parameter for sand. For sand, density is determined by multiplying the relative density (specific gravity) of the sand times the density of water. Bulk Density of Sand. The bulk density or unit weight of sand is the mass or weight of the sand that required to fill a container of a specified unit volume.
2018-10-30 · coarse aggregate. The specific gravity may be expressed as bulk oven dry (OD) specific gravity, bulk saturated surface dry (SSD) specific gravity, or apparent specific gravity. The bulk (SSD) specific gravity and absorption are based on aggregate after 15 to 19 hours soaking in water.
