通告描述：

This Draft Uganda Standard 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 test 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 6. It is not applicable to concretes made with lightweight aggregates, air-cooled blast-furnace slag, or aggregates of high porosity. In these cases, Test Method C173/C173M should be used. This test method is also not applicable to non-plastic concrete such as is commonly used in the manufacture of pipe and concrete masonry units.
