THE INFLUENCE OF TIME OF MIXING ON QUALITY OF CONCRETE MIXES

EINFLUSS DER MISCHDAUER AUF DIE BETONMISCHGUETE

In the course of a research programme at the Institute for Construction Equipment at the University of Karlsruhe three types of mixer were studied: open-pan, drum type and turbo drive mixers. The influence of the mixing time on four parameters (water content, fine dust content, retention of grains on the 2 mm sieve, retention of grains on the 16 mm sieve), was determined. In order to achieve a good mix design it is recommended (in addition to the provisions of DIN 1045) that a minimum and a maximum mixing time should be specified as well as the specification of a size factor for the mixing system.
