Tests for mechanical and physical properties of aggregates - Part 6: Determination of particle density and water absorption; German version EN 1097-6:2000 + AC:2002 + A1:2005
This European Standard specifies methods for the determination of the particle density and water absorption
of aggregates The first five methods are applicable to normal aggregates with a sixth method for
lightweight aggregates.
The principal methods specified are:
a) a wire basket method for aggregates passing a 63 mm sieve but retained on a 31.5 mm
sieve;
h) pyknometer methods for aggregates passing a 31,5 mm sieve but retained on a 0 062, mm
sieve.
NOTE I The wire basket method may be used as an alternative to the pyknometer
method for aggregates between 4 mm and 31,5 mm. In case of dispute, the
pyknometer method described in clause 8 should be used as the reference method.
NOTE 2 The wire basket method carl also be used for single aggregate particles
retained on a 63 mm sieve, ii
A method for' the determination of pre-dried particle density of dense aggregates is specified in annex A.
NOTE 3 As the absorption of dense aggregates is Iow, pre-dried particle density can be
determined directly in water. This method is different to the determination of particle density on
an oven dried basis.
A modified version of the wire-basket method suitable for determining the particle density and water
absorption of coarse aggregates saturated to constant mass is specified in annex B.
For lightweight aggregates, a modified version of the pyknometer test specified in annex A is specified in
annex C.
