Bulk Density Of Aggregates  Loose And Compact Bulk ... Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume. It depends on the packing of aggregate i.e. Either loosely packed aggregates or well dense compacted aggregates . EXAMPLE USING ABSOLUTE VOLUME METHOD  CONTINUED  . For the cement, water, and coarse aggregate, the absolute volumes can be calculated using the following equation: where: W = G = 62.4 = weight of the material specific gravity of the material weight of water per cubic foot By substitution into this formula, the absolute volumes of the cement, water, and coarse aggregate are calculated as follows: l l l 7.

Aggregate in Concrete  The Concrete Network
Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings.

Coarse Aggregate Specific Gravity  Pavement Interactive
For a particular aggregate type or source, fine aggregate specific gravities can be slightly higher than coarse aggregate specific gravities because as the aggregate particles get smaller, the fraction of pores exposed to the aggregate surface (and thus excluded from the specific gravity calculation because they are waterpermeable) increases.
