Air-entraining Agent

Concrete high-efficiency air-entraining agent is a hydrophilic surfactant. When added to concrete, it can introduce independent, closed, uniform and fine air bubbles, effectively improving the workability of concrete and significantly enhancing its durability. The high-efficiency air-entraining agent products of our company include BR-I and BR-II series products, forming an air-entraining agent product system with different air-entraining and air-stabilizing performance gradients. The series of products can introduce a large number of closed, uniform and fine air bubbles into concrete at low dosage. The introduced air bubbles have stable performance. After standing for 1 hour, the air content loss is less than 1%. After pouring and vibration, the air content loss is small. It can significantly improve the frost resistance, impermeability, deicing salt resistance and chemical erosion resistance of concrete, and effectively extend the service life of the structure. Our series of products are widely used in mortar and concrete projects in water conservancy, transportation, municipal, industrial and civil buildings, as well as in special projects with high durability requirements.
