This method covers determination of the air content of freshly mixed concrete from observation ofthe change in volume of concrete with a change in pressure.

This method is intended for use with concretes and mortars made with relatively dense aggregatesfor which the aggregate correction factor can be satisfactorily determined by the techniquedescribed in Section 5. It is not applicable to concretes made with light-weight aggregates, aircooledblast-furnace slag, or aggregates of high porosity. In these cases, T 196M/T 196 should beused.
