Applies to concrete in accordance with DIN 1045 with a maximum particle size of the aggregate up to 63 mm, and also to concrete in accordance with the 'Directives for Light-weight Concrete and Reinforced Light-weight Concrete with Closed Texture', June 1973 edition. This Part deals with the compaction of freshly mixed concrete with the aid of internal vibrators of types in common use today.
