What is the mechanism of adding air-entraining agents to improve the durability of concrete?

Air-entraining agent is one of the chemicals. It has good bubble structure, small bubble radius, and high frost resistance index. It is used in high-durability concrete structures, such as dams, high-grade highways, thermal power station cooling towers, pool hydraulics, ports, etc. It is also a commonly used additive to improve the durability of concrete pavements.…
