Discharge the material and sieve the aggregate over a sieve coarser than a (No. 12) sieve (Figure 13). Figure 13: Sieving the sample after the abrasion test. Sieve the finer material on a No. 12 ( mm) sieve. Wash the aggregate coarser than the No. 12 ( mm) sieve and ovendry to a constant mass at 230ºF (110ºC).

The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between with a corresponding particle (mass) density of kg/m 3 (150181 lb/ft 3).

The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight Specific gravity is a measure of a material''s density (mass per unit volume) as compared to the density of water at °F (23°C). . 4 ( mm.
Fine aggregate (sometimes just referred to as "fines"). Defined by the Asphalt Institute (2001{{2}}) as the fraction of aggregate passing the mm (No. 8) sieve. Defined by AASHTO M 147 as natural or crushed sand passing the No. 10 ( mm) sieve and mineral particles passing the No. 200 ( mm) sieve. Coarse aggregate.
Specimens with 14‐mm maximum aggregates size did not exhibit consistent aggregate size effect when compared with the 7‐mm and 20‐mm maximum aggregate size specimens with nominal spalling depths of mm and mm for specimens LP‐14‐B and LP‐14‐G as shown in Table 3.

Aggregate can be classified as fine or coarse aggregate. Fine aggregate is generally natural sand and is graded from particles 5mm in size down to the finest particles but excluding dust. Coarse aggregate is natural gravel or crushed stone usually larger than 5 mm and usually less than 16 mm in ordinary structure [1, 7, 9, 28, 29].
Typically, coarse aggregate sizes are larger than mm (5 mm in British code), while fine aggregates form the portion below mm. A maximum size up to 40 mm is used for coarse aggregate in most structural applications, while for mass concreting purposes such as dams, sizes up to 150 mm .
