Batching, Mixing, Transporting, and Handling Concrete, Chapter 10

BATCHING Batching is the process of measuring concrete mix ingre-dients by either mass or volume and introducing them into the mixer. To produce concrete of uniform quality, the ingredients must be measured accurately for each batch. Most specifications require that batching be done by mass rather than by volume (ASTM C 94 or AASHTO M 157).
