Air-entrained concrete is typically specified in areas of the country where frost-related damage can occur. The measurement of air content in fresh concrete of normal density is typically performed using the pressure method ().Another useful test is ASTM C 173.However, the pressure method is frequently preferred because it is relatively fast.

Concrete Mixing Methods and Concrete Mixers: State of the

Apr 01, 2001 · Abstract. The performance of concrete is determined by its microstructure. Its microstructure, in turn, is determined by its composition, its curing conditions, and also by the mixing method used to process the concrete. This paper gives an overview of the various types of mixing methods used by the concrete industry.
