Air-entraining agents (AEAs) are additives used in the concrete mix to create tiny air bubbles within the cement paste. These agents enhance the workability of concrete and significantly increase its resistance to freeze-thaw cycles, thus improving durability. AEAs are particularly valuable in regions with severe weather fluctuations that expose concrete to extreme freeze-thaw conditions. The introduction of air voids reduces the concrete’s density and improves its insulative properties, while also providing spaces to accommodate the expansion of water upon freezing, thereby preventing crack formation and structural damage.
