Place concrete to be tested in material container (1) in three equal layers. Rod each layer 25 times, as directed in making compressive test cylinder specimens. Excess concrete should be removed by sliding strike-over bar (3) across the top flange, using a sawing motion, until container is just level-full. 2.

For a severe freeze-thaw exposure, Table 9-5 recommends a target air content of 6.0% for a 25-mm aggregate. Therefore, design the mix for 5% to 8% air and use 8% (or the maximum allowable) for batch proportions. The trial-batch air content must be within ±0.5 percentage points of the maximum allowable air content.
