Fine Aggregates Specific Gravity of Sand / Fine

12/12/2020 Fine aggregate Specific gravity or Specific gravity of sand is the ratio of the weight of a given volume of fine aggregate (sand) to the weight of an equal volume of water. The Fine aggregate Specific gravity is often considered to be 2.65. For road construction, fine aggregate has a wide range from about 2.5 -3.0 but on average 2.68.

With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter. Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.
