   en.wikipedia.org/wiki/Volumetric_concrete_mixer

   Volumetric concrete mixers can produce exactly the amount of concrete needed when it is needed at any time. [1] Some concrete suppliers offer general purpose concrete batched in a volumetric mixer as a practical alternative to ready-mix if quantities and schedules are not fully known, to eliminate waste and prevent premature stiffening of the mix.

5. Ready-mix concrete - Wikipedia

   en.wikipedia.org/wiki/Ready-mix_concrete

   For a small to medium project, the cost and time of hiring mixing equipment, labour, plus purchase and storage for the ingredients of concrete, added to environmental concerns (cement dust is an airborne health hazard) [10] may simply be not worthwhile when compared to the cost of ready-mixed concrete, where the customer pays for what they use ...

   A variant of standard concrete transportation is the concrete (or, cement) mixing trailer. These small versions of transit-mix trucks are used to supply short loads of concrete. They have a concrete mixing drum with a capacity of between 0.76 and 1.34 cubic metres (1 and 1.75 cu yd).
