Technical data:
The aggregate is the filling materials of concrete. The usage of aggregate can increase concrete’s volume, decrease the necessary amount of concrete as well as its shrinkage. In the meantime the aggregate provides stability and abrasion resistance for concrete’ size.
Apparent Specific Gravity: the ratio of the weight in air of a unit volume of the impermeable portion of aggregate at a stated temperature to the weight in air of an equal volume of gas-free distilled water at a stated temperature.
Bulk Specific Gravity: the ratio of the weight in air of a unit volume of aggregate (including the permeable and impermeable voids in the particles, but not including the voids between particles) at a stated temperature to the weight in air of an equal volume of gas-free distilled water at a stated temperature.
Bulk Specific Gravity (SSD): the ratio of the mass in air of a unit volume of aggregate, including the mass of water within the voids filled to the extent achieved by submerging in water for approximately 15 hours (but not including the voids between particles) at a stated temperature, compared to the weight in air of an equal volume of gas-free distilled water at a stated temperature.
In order to save the soaking time of the fine-grained aggregate, we recommend to use the vacuum extraction method.
