Air-Entraining Agent (Sodium Lauryl Sulfate K12, AOS, etc.)

 An air-entraining agent is a hydrophobic surfactant that can be dissolved in water and added to the concrete mixture to generate a large number of tiny air bubbles during the mixing process. The air-entraining agent can improve workability, water retention and cohesion of the concrete mixture, improve fluidity of the concrete, and introduce a large number of uniformly distributed, closed and stable micro-bubbles during the mixing process.
