ratio of the weight of free-water in the mix to the weight of cement in the mix. It is computed on a weight basis by simply dividing the weight of the water in the mix by the weight of the cement in the mix. For example, for a mix containing 282 pounds of water and 564 pounds of cement the water-cement ratio would be: w/c = 282 lbs / 564 lbs = 0.5

Concrete Mixing Methods and Concrete Mixers: State of the Art

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.
