What it is
The aggregate is conditioned, weighed in the required dry/saturated states and its displaced water volume is determined.
SANAS T1018
Public test guide
Compares the dry aggregate mass with the mass of an equal volume of water, including permeable particle pores.
Plain-language explanation
The project specification controls the exact method and acceptance requirement.
The aggregate is conditioned, weighed in the required dry/saturated states and its displaced water volume is determined.
Prepared aggregate, balance, water bath or pycnometer arrangement, drying oven and absorbent cloth where required.
Dry bulk relative density and related absorption information for the tested fraction.
Used in concrete and asphalt mixture calculations, yield control and conversion between mass and volume.
Typical test sequence
Condition the aggregate as specified
Record dry, saturated-surface-dry and immersed/volume readings
Calculate relative density and absorption
