Technical Questions

ACI Committees, Membership, and Staff have answered common questions on a variety of concrete related topics.

Is density a good indicator of air content?

Q. Is density a good indicator of air content?


A. Yes. Density tests on freshly mixed concrete provide information on the level of air content (ASTM C138). Because air content has a large effect on the properties of concrete, density tests provide additional useful information to the air meter measurements.
