Volume 19/Number 1 Control of Air Content in , - Know More
Entrained air is produced during mechanical mixing of concrete that contains an air-entraining admixture The shearing action of mixer blades continuously breaks up the air into a fine system of bubbl Air-entrain-ing admixtures stabilize these air bubbl Air-Void System Once the concrete has set, the casts of the original air bubbles are left be-hind in the hardened concrete ,...
