What are air-entraining agents and air-entraining water-reducing agents? What are their functions?

Air-entraining agent is an admixture that can introduce a large number of evenly distributed, stable and closed micro-bubbles during the concrete mixing process. Air-entraining water-reducing admixture is an admixture with the functions of air-entraining agent and water-reducing agent.

Air-entraining agents can reduce the solid-liquid-gas phase interfacial tension, increase the strength of the bubble film, and produce fine, evenly distributed microbubbles in the concrete that can still be retained after hardening. These bubbles can improve the workability of the concrete mixture and improve the frost resistance, impermeability and erosion resistance of the concrete. The use of air-entraining agents is an important discovery in the history of concrete development because it improves the workability of concrete, extends the service life of concrete, and increases the durability of concrete. Therefore, air-entraining agents must be used in concrete such as hydraulic engineering, ports, and highways. With the development of admixture technology and its application, the application of air-entraining water-reducing admixtures and high-efficiency air-entraining water-reducing admixtures has become more common. Because this not only avoids the disadvantage of using air-entraining agents alone to reduce the strength of concrete, but also has the advantage of comprehensively improving the performance of concrete. Its application will surely improve the comprehensive social and economic benefits of concrete projects more comprehensively.
