Standard Method of Test for Air Content of Freshly Mixed Concrete by the Pressure Method (ASTM Designation: C 231-08c)
standard by American Association of State and Highway Transportation Officials, 2010

Category: AASHTO

Description

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. This test method is also not applicable to nonplastic concrete such as is commonly used inthe manufacture of pipe and concrete masonry units.
