Although the main problem is caused by the mixing plant, the misuse of the mixer truck during the transportation also will cause the problem, especially by the new driver.
3. The drum rotates too fast to cause the problem. If the driver turns the drum rotating too fast, the heavier material as blinding will sink under the centrifugal force.
Many people think the mixer drum is bigger that concrete segregation happens easier. It's not true. It's not because of the size of the mixer drum, but the unqualified design of the drum, especially the unqualified design for the assembly angle of the fins and the other unqualified machining. The mixer drums made by some small refitting factory with unqualified design may have the problem of the concrete segregation because the fins cannot stir the materials equably. So try to buy the mixer truck from the big and famous factory. The mixer drum made by the big factory normally doesn't have the problem.
