Cement Standards and Concrete Standards - ASTM International
ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
Batching, Mixing, Transporting, and Handling Concrete ...
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).
