Tests for mechanical and physical properties of aggregates - Part 6: Determination of particle density and water absorption (consolidated version)
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;
b) pyknometer methods for aggregates passing a 31,5 mm sieve but retained on a 0,063 mm sieve.
NOTE 1 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
the reference method.
NOTE 2 The wire basket method can also be used for single aggregate particles retained on a 63 mm sieve.
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 low, pre-dried particle density can be determined directly
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
annex C.
Diese Europäische Norm legt folgende Verfahren für die Bestimmung der Rohdichte und der Wasseraufnahme von Gesteinskörnungen fest. Sie gilt für Gesteinskörnungen mit einer Rohdichte über 1 Mg/m3. Die festgelegten Verfahren sind: a) Drahtkorbverfahren für Gesteinskörnungen, die durch ein 63-mm-Sieb hindurchgehen, jedoch von einem 31,5-mm-Sieb zurückgehalten werden; b) Pyknometer-Verfahren für Gesteinskörnungen, die durch ein 31,5-mm-Sieb hindurchgehen, jedoch von einem 0,063-mm-Sieb zurückgehalten werden. ANMERKUNG: Das Drahtkorbverfahren kann auch für einzelne Gessteinskörnungen angewendet werden, die von einem 63-mm-Sieb zurückgehalten werden.
