Concrete mix design for high strength self-compacting ...

2014-8-1  A number of mix design methods for SCC had been proposed earlier and they differ considerably from the regular conventional concrete design. Okamura [18] and Ouchi et al. [19] were the first to propose a generalized method for SCC wherein concrete is considered to be a two phase material consisting of coarse aggregate and mortar.

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.
