Concrete Mixing Methods and Concrete Mixers: State of the Art

Apr 01, 2001  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.

Factors Affecting Workability of Concrete - Civil Engineering

Rich concrete mix (cement content is high) is more workable because due to sufficient cement aggregates will have proper lubrication for easy movement which means more workability. Size of Aggregates Finer particles require more water for a larger surface, hence aggregate with finer particles need more water to make it workable.

Mixing (process engineering) - Wikipedia

In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous.Familiar examples include pumping of the water in a swimming pool to homogenize the water temperature, and the stirring of pancake batter to eliminate lumps (deagglomeration).. Mixing is performed to allow heat and/or mass ...
