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. agent.
Air-entraining agent refers to the introduction of a large number of evenly distributed micro-bubbles during the concrete mixing process to reduce bleeding and segregation of the concrete mixture and improve the mixing and mixing of concrete. It is an admixture that has good workability and can significantly improve the frost resistance and durability of hardened concrete. At present, the most commonly used air-entraining agents are rosin thermopolymers, rosin soaps, alkyl benzene sulfonates, etc. Due to the existence of a large number of tiny, closed and evenly distributed bubbles, certain properties of concrete are significantly improved or changed.
