Concrete mixtures were mixed in a revolving drum laboratory mixer in accordance with ASTM C192. Fresh concrete was tested for slump (ASTM C143), temperature (ASTM C1064), air content by the pressure method (ASTM C231), and density (ASTM C138). The setting time of the concrete mixtures was estimated from

Concrete Acceptance Testing - NRMCA

ACI 301-20 and ASTM C94 require the density to be measured in accordance with ASTM C138. This test provides useful information about the quality of concrete and potentially causes for low strength test results. The density is also used to determine yield that can be compared to the quantity ordered.

Computing and Measuring Yield| Concrete Construction Magazine

The yield of the concrete is simply this actual, measured volume divided by the reported volume. So, let’s say our example mix arrived 1.5% low on air content. If you performed the C138 density test onsite it would come in at 141.6 lb/cubic foot. Dividing 7533 pounds (the batch weight) by 141.6 (the measured unit weight) gives us a volume in
