Specific gravity and Water Absorption Test of Aggregate major important test to be performed on aggregate. These two parameters or property of aggregate play an important role in the mix design of concrete.As we know that aggregate occupies 70 to 80% volume of concrete, it testing becomes essential before use.
SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85
1 SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85 GLOSSARY Absorption: The increase in weight due to water contained in the pores of the material. Bulk Specific Gravity (also known as Bulk Dry Specific Gravity): The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume

Bulk specific gravity (oven-dry basis), Gc. Use this procedure for hot mix asphalt aggregates, aggregate base, and cement treated base aggregate. B C A Specific Gravity
Determining the specific gravities of coarse …
01-03-2009 · Specific gravity of coarse aggregates is measured at the bulk dry, saturated-surface dry and apparent conditions. The Gsb (dry) is the specific gravity when water is considered to have penetrated all the effective voids in the coarse aggregate while the apparent specific gravity (Gsa) determines the specific gravity without factoring any penetration of water into the permeable voids.
