Batching, Mixing, Transporting, and Handling Concrete ...

If concrete has been adequately mixed, samples taken from different portions of a batch will have essentially the same density, air content, slump, and coarseaggregate content. Maximum allowable differences to evaluate mixing uniformity within a batch of ready mixed concrete are given in ASTM C 94 (AASHTO M 157).
