This method covers determination of the air content and sequential air method (SAM) number of freshly mixed concrete from observation of the change in volume of concrete with a sequential change in test pressure.
This method is intended for use with concretes and mortars made with aggregates for which the aggregate correction factor can be satisfactorily determined by the technique described in Section 7. It is not applicable to concretes made with light-weight aggregates, air-cooled blast-furnace slag, or other aggregates with high porosity. This test method is also not applicable to non-plastic fresh concrete such as is commonly used in the manufacture of pipe and concrete masonry units.
This standard was formerly designated as provisional method of test TP 118.
