Density of Aggregate
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/m3 (150181 lb/ft3)....

Essential Points. Most of the aggregates possess a relative density within – with a similar particle density about Kg/m 3 (150181 lb/ft 3).; Hereabouts, for coarse aggregates, the standard test process has been described in ASTM C 127(AASHTO), and for fine aggregates, the standard test practice has been described in ASTM C 128 (AASHTO)....
Bloating Mechanism of Lightweight Aggregates due ...
17/04/2019 · Figure 5 is a graph of bulk density and water absorption ratio of an artificial lightweight aggregate produced by a rapid sintering method. Bloating was started at 1100°C, and it shows bulk density of about g/cm 3. With the increase of the firing temperature, the bulk density decreased and the water absorption ratio also decreased by 14%....
