Abstract：Air entraining agent plays an indispensable role in solving the workability，freeze resistance and impermeability of concrete. Based on the definition and principle of air entraining agent，this paper analyzes and researches the domestic and foreign patents of the air entraining agents，and summarizes the research progress of domestic and foreign patents of air entraining agents and the effects of air entraining agent on workability，frost resistance and durability of concrete. It will help to understand the development of the domestic and foreign air entraining agents and further develop a new high performance，functional and environmental friendly air entraining agent.
