NBN EN 1097-6:2000

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.
