Evaluation Efficiency of a Vessel-Shaped Concrete Mixer Using a Visual Technique

One of the problems of high performance concrete is that the mixing time of this concrete is normally longer than that of conventional concrete, because the amount of powder used is much larger. It is necessary to develop a high performance mixer in order to reduce the mixing time. This research aims to evaluate the mixing efficiency on the vessel shape of a bi-axial forced mixing type mixer. The authors have developed and proposed a visualization technique that makes it possible to measure the degree of mixing with lapse time. The technique involves a visual model of concrete mixing in a container, and how to count the number of particles of model aggregates. The results showed that the mixer having a shallow container shape and many blades excels in terms of pattern flow with both globally circulating flow and locally crossing flow as compared with the mixer having a deep vessel shape.
