Air-entraining admixtures are specialized concrete additives that introduce microscopic air bubbles into the concrete mix. These air bubbles serve various purposes, and the resulting air-entrained concrete exhibits improved durability and resilience, particularly in freezing and thawing conditions. Properly air-entrained concrete is more resistant to cracking and scaling caused by the expansion of water during freezing conditions.
