Testing for Air in concrete| Concrete Construction Magazine

The only ingredient in the concrete that is compressible is the air. Cementitious material, water, and aggregates do not respond to the small rise in pressure. So the pressure change is correlated to the air content of the concrete. Entrained air is formed in concrete using a surfactant. The smaller the bubble, the stronger the bubble.

HC mass in pore volume is decreasing, so it is the differential process that is contrary to Moses' [8] belief that this is a flash process. At point 5, HCPV remains constant as in steps 1 to 4, the oil volume has changed and the system is into a two-phase region.

Effect of Air Entrained Concrete on Strength of Concrete

Typically, it may be assumed that a loss of 5% in compressive strength of concrete occurs due to each 1% by volume of entrained air in the concrete mix. In order to estimate water-cement ratio required for an air entrained concrete, an allowance for strength reduction is incorporated in the mix design and higher target mean strength is assumed.
