Tests for geometrical properties of aggregates - Part 6: Assessment of surface characteristics - Flow coefficient of aggregates
This European Standard specifies the reference method used for type testing, and in case of dispute,
for determining the flow coefficient of coarse and fine aggregates. For other purposes, in particular
factory production control, other methods may be used provided that an appropriate working
relationship with the reference method has been established. Examples of advanced test methods
can be found in the Bibliography.
This European Standard applies to coarse aggregate of sizes between 4 mm and 20 mm and to fine
aggregate of size up to 2 mm.
NOTE 1 For coarse aggregates between 4 mm and 20 mm, the flow coefficient is linked with the percentage
of crushed or broken surfaces of an aggregate and can therefore be used in association with the method
specified in EN 933–5. Shape and surface texture characteristics also influence the result.
NOTE 2 Experience of this test has been generally limited to natural aggregates.
