What it is
Conditioned aggregate mass and displaced water volume are measured under controlled conditions.
Public test guide
Apparent relative density
Measures relative density using only the solid particle volume and excluding permeable pores.
Plain-language explanation
What the test tells you.
The project specification controls the exact method and acceptance requirement.
What is used
Representative aggregate, calibrated balance, water bath or pycnometer and drying equipment.
What it determines
Apparent relative density of the aggregate particles.
Why it matters
Supports material characterisation and mixture calculations where particle density is required.
Typical test sequence
From sample
to result.
- 01
Prepare and condition the sample
- 02
Obtain the required mass and water-displacement readings
- 03
Apply the method calculation for apparent relative density
