Batching Mixing Transporting And Handling Concrete

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