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.Learn More
