CIVL 1101 - Part 9 - Handling and Placing

Batching and Mixing. Batching-- Batching of aggregates and cement should always be done by weight. Other components, like water and admixtures, can be batched by volume. Batching by weight allows rapid and convenient adjustment of mix parameters if desired. Material quantities should be measured with a high degree of accuracy.

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).
