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.

It is delivered to a worksite, often in truck mixers capable of

What is the difference between RMC and mix design ? - Quora

Answer (1 of 3): Mix design- Proportioning of water, aggregate and cement used to produce a concrete mix to achieve the desired strength, workability and durability. ("design" to obtain desired concrete "mix") If we know the quantitaive parameters such as targeted compressive strength of concret

RMC - A Revolution in Production of Concrete

RMC is a specialized material in which the cement aggregates and other ingredients are weigh batched at a plant Figures 1 and 2 in a central mixer or truck mixer, before delivery to the construction site in a condition ready for placing by the builder. Samples are also taken for determining actual compressive strength of concrete. Three
