Air entraining agent is an important independent type of concrete admixture. Its main function is to greatly improve the frost resistance durability of concrete. In addition, the air entraining agent has significant improvement effect on the construction performance and other comprehensive durability of concrete. At present, the traditional domestic commercial air entraining agent is mainly rosin soap and rosin hot polymer, which has the disadvantages of poor solubility of products, poor compounding with other additives, and large reduction of concrete strength.
