Mixing technology for lightweight concrete
The demand for high-quality mixes is increasing. Meeting this demand is often difficult, if not impossible. The reason for this is that mixing processes, as described in the literature, are always subject to a segregation process. Investigations carried out with various conventional mixing systems show, according to Eirich, that mixing should not take place for an unrestricted period of time. The best mix quality attainable in a certain mixing time depends on the mixing system used: if mixing takes longer, the quality decreases, segregation takes place, and the optimum mix quality cannot be...
