These air bubbles increase the workability of the concrete in the course of placement and improve its durability when hardened, particularly in locations at risk of freeze-thaw cycles. In contrast to foam concrete, that is lightweight and designed by introducing secure air bubbles utilizing a foam agent, air-entrained concrete maintains its density (air includes six–twelve vol.
