For fine aggregate testing thoroughly mix the sample and reduce it to obtain one 1000 g ± 10 gram sample for apparent specific gravity and two 500 g ± 3 gram samples for bulk specific gravity determination For aggregate reduction use the appropriate procedures described in T 248 106328172 Coarse aggregate samples (Method B)...

Overview The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water It is similar in nature to the coarse aggregate specific gravity test Figure 1: Fine aggregate specific gravity sample and pycnometer...

Typically, coarse aggregate sizes are larger than 475 mm (5 mm in British code), while fine aggregates form the portion below 475 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 may be used...
