Transit Mix vs Central Mix vs Shrink Mixed Concrete
The number of revolutions needed to complete the mixing of shrink mix concrete in the truck mixer varies depending on the size of the central mixer vessel and the duration of mixing or co-mingling of all of the ingredients (often less than 90 seconds), but generally about 30 turns of the mixer truck drum produces mix uniformity throughout the load.

ADVANTAGES OF CONCRETE CENTRAL MIX VS TRANSIT MIX - DHE
The cost of a central concrete mixing plant is 2X the cost of a transit mix plant. Typically the cost of a central concrete mixing plant is justified for a plant market of 100,000 yards per year and more. The payback of the extra cost of the central mix plant can be as short as 3 – 5 years.

Additionally, transit-mixing allows concrete to be hauled to construction sites further away from the plant. A disadvantage to transit-mixed concrete, however, is that the truck capacity is smaller than that of the same truck containing central-mixed concrete. Shrink-mixed concrete is used to increase the truck's load capacity and retain the ...
CENTRAL vs DRY MIX CONCRETE PLANTS - a discussion
Concrete that is partially mixed in a plant mixer and then discharged into the drum of the truck mixer for completion of the mixing is called shrink mixed concrete. Central mixing plants that include a stationary, plant-mounted mixer are often actually used to shrink mix, or partially mix the concrete.
Ready Mixed Concrete - Types and Advantages
Ready mix concrete is a special concrete mixer used for mass concrete construction with great quality control.
