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

Relative yield is the ratio of the actual volume of concrete obtained to the volume as designed for the batch. It is understood as a 1:1 ratio. If the relative yield calculates out to 1.00 or greater, then the yards delivered is equal to or greater than what was ordered.

What Yield Can Do For You Concrete Construction Magazine

2009-11-9  Yield is determined as batch weight divided by density. This is converted to relative yield, which is the total volume of the concrete received divided by the volume the producer intended to provide. If relative yield is 1.00, then it's exactly the same. But this is expressed as cubic feet per cubic yard.
