density is greatly depending on the specific gravity. A porous nature (i.e. those which increase in weight exceeding 10% of dry weight after immersion for 24 hours) should not be permitted, unless specified. The range of specific gravity for aggregates should be between 2.4 and 2.9.
The Density of Sand utility returns sand density based on sand conditions (wet/dry in bulk / packaged).. The density of the sand is affected if the sand is compacted (bulged) or loose and if it is wet or dry.When packed, the grains of sand are forced to form a narrower formation, and more matter is in the volume.. Natural sand i.e. locally available River sand having a bulk density of 1.71 kg ...
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.
Specific Gravity of Aggregate. Specific Gravity is defined as the ratio of Weight of Aggregate to the Weight of equal Volume of water. The specific gravity of an aggregate is considered to be a measure of strength or quality of the material. Aggregates having low specific gravity are generally weaker than those with high specific gravity.
