Air Entraining Agent
ST-304
Air Entraining Agent ST-304 is a specially formulated admixture designed to introduce stable, microscopic air bubbles into concrete, enhancing its workability, freeze–thaw resistance, and long-term durability. The controlled air content improves cohesiveness and reduces bleeding, resulting in lighter, more resilient concrete with smoother finishing characteristics.
