How to determine concrete yield

w = total weight of mixing water added to batch, in pounds; and W = weight of concre t e , in pounds per cubic foot. To calculate yield the following formula should be used: Y = s___ , in which n Y = yield of concrete produced per 94-pound bag of cement, in cubic feet; S = volume of concrete produced per batch …

Moisture Control in Concrete Production | Agg-Net

The resulting concrete will be consistent batch after batch, improving product quality and reducing wastage or spoilt materials. Moisture control can easily be installed in new or existing plants, with the return on investment often being seen just months after installation, depending on the output of the plant.

ASTM C138 - ACI Density, Yield, and Air Content of Concrete ...

To figure out the density, you are filling up a container with concrete. This container must have a known volume (4), minimum .20 cubic feet. First weigh the empty container (1) and record that value to the nearest tenth (.1) of a pound. After performing the proper procedures for filling the container (i.e. filling it in three lifts, mallet blows, rodding, striking off with strike-off plate), follow these steps:
