Specific Gravity and Water Absorption Tests on Aggregates

Formulas: (1) Specific gravity = W 3 / (W 3 – (W 1 – W 2)) (2) Apparent specific gravity = W 4 / (W 4 – (W 1 1 – W 2)) (3) Water Absorption = ((W 3 – W 4) / W 4) X 100** The size of the aggregate and whether it has been artificially heated should be indicated. ** Though high specific gravity …

Percent Voids for Gravel - Earthwork/grading engineering ...

Aug 02, 2008· I'd use 1/3rd. Bear in mind that you can also measure it yourself. Take the specific gravity of the aggregate, multiply it by the unit weight of water and that would be the density if there were no voids. Then take the bulk density of the aggregate and figure out how much is lost to air voids. Example: Specific gravity …

Density (Specific Gravity) - an overview | ScienceDirect ...

Specific gravity is the (unit less) ratio of the solid wood density to the density of water at the same temperature. The solid wood density may be determined using the green volume, the ovendry volume, or intermediate volumes. This is notable as wood shrinks about 8%–15% as it dries. The basic specific gravity …
