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.
It has the characteristics of reducing the surface tension of the solution, producing closed and independent bubbles, high foaming multiple, many bubbles, small bubble spacing, long foam stabilizing time, which can significantly improve the working performance of plastic concrete and improve the durability of hardened concrete. It is a high-quality air entraining agent with great application prospect in domestic concrete engineering.
