Abstract

This research aims to increase the mixing efficiency of a bi-axial forced mixing type mixer so as to produce concrete without compromising the specific property intended for placing or after hardened. The arranged paddle angle and the installed blade angle of a developed model mixer were varied to investigate the flow pattern of simulating model concrete during mixed with the help of a visualization technique. The visualization technique allowed a macro-mixing efficiency to be evaluated by the movement of tracer particles which simulated coarce aggregate particles during mixed. The change in the distance between position of the tracers' gravity and the central position was measured with mixing time elapsed. The applicability of the finding in the mixing test using the model concrete to the mixing efficiency of actual mixer was proved by the mixing test using actaul concrete.
