Concrete Mixing Methods and Concrete Mixers: State of

2001-4-1  2.1.2 Pan Mixers . All pan mixers work on basically the same principle []: a cylindrical pan (fixed or rotating) contains the concrete to be mixed, while one or two sets of blades rotate inside the pan to mix the materials and a blade scrapes the wall of the pan.The shapes of the blades and the axes of rotation vary. Figure 4 shows the different combinations of blade configurations and pan.

2001-5-23  As for all materials, the performance of concrete isdetermined by its microstructure. Its microstructure isdetermined by its composition, its curing conditions,and also by the mixing method and mixer conditionsused to process the concrete. The mixing procedureincludes the type of mixer, the order of introduction ofthe materials into the mixer, and the energy of mixing(duration and power). To control the workability or rhe-ology of the fresh concrete, for example, it is importantto control how the concrete is processed during manu-facture. In this overview, the different mixers commer-cially available will be presented together with a reviewof the mixing methods. Further, the advantages anddisadvantages of the different mixers and mixing
