weigh method batching of concrete

Unit Weight (ASTM C 138) - 14071_298

Unit Weight (ASTM C 138) The unit weight, or density, of concrete varies with the amount and density of the aggregate, the amount of entrapped or entrained air, and the water and cement contents. Conventional concrete used in structures, such as buildings and pavements, has a unit weight in the range of 140 to 150 pounds per cubic foot (pcf).

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).
