Air-Entrainment

The use of an air-entrained agent as an admixture to a Portland concrete mixture.  Air-entrainment will increase frost resistance.

An air-entrained agent will cause small bubbles to be formed in the concrete during mixing. This allows the process of climatic freezing and thawing to occur without damaging the hardened concrete.

The air content of a concrete mixture can be easily determined by using an air meter.
