This method covers determination of the air content of freshly mixed concrete from observation of
the change in volume of concrete with a change in pressure.
This method is intended for use with concretes and mortars made with relatively dense aggregates
for which the aggregate correction factor can be satisfactorily determined by the technique
described in Section 5. It is not applicable to concretes made with light-weight aggregates, aircooled
blast-furnace slag, or aggregates of high porosity. In these cases, T 196M/T 196 should be
used. This test method is also not applicable to nonplastic concrete such as is commonly used in
the manufacture of pipe and concrete masonry units.
