Concrete Manual Tests: Air Content Tests Mobile App

Accurate determination of the air content is essential in computations of cement content and yields, as well as a check for compliance with Specification 2461.4A4b limitations on the air content itself. The air test is subject to the variations and limitations of each batch; therefore, spread the tests out over the entire period of the placement operation. The Concrete Manual Tests: Air Content Tests walks you through conducting an air test.
