· Values for absorption and bulk specific gravity (SSD) may be significantly higher for aggregate not oven dried before soaking than for the same aggregate treated in accordance with 8.1. This is especially true of particles larger than 75 mm (3 in.) since the water may not be able to penetrate the pores to the center of the particle in the prescribed soaking period.

A general way to estimate this is by percentage as follows: if you have 4.5cubic metres concrete at a ratio of 1:2:3, total units of cement and aggregates is 6. For cement we therefore have. 1/6 x 4.5CM=0.75CM of cement. Density of cement=1440kg/cubic m. Therefore mass=1440x0.75=1080kg.

1.1 This test method covers the determination of specific gravity and absorption of 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.
