High-effciency air-entraining agent for concrete is a hydrophilic surfactant that can introduce independent, closed, uniform and fine air bubbles when mixed into concrete, effectively improving the workability of concrete and significantly improving the durability of concrete. 

This product can introduce a large number of closed, uniform and fine bubbles into concrete at a low dosage. The performance of the introduced bubbles is stable. 

The loss of air content is less than 1% after standing for 1 hour. The loss of air content is small after pouring and vibrating. It can significantly improve the ability of concrete to resist frost, seepage, deicing salt and chemical erosion, and eectively prolong the service life of the structure. 

This series of products are widely used in mortar and concrete projects such as water conservancy, transportation, municipal administration, industrial and civil construction, especially special projects with high durability requirements, such as hydropower stations.
