Sodium α-alkenyl sulfonate is a kind of ionic surfactant, which has the function of entrained air in concrete. In the process of mixing concrete, many fine bubbles with uniform distribution, stability and closure can be introduced to improve the workability of concrete, and increase the anti-freezing and anti-seepage properties of concrete.

1, in the concrete production process, a large number of bubbles can be introduced; 2, improve the workability of concrete mix; 2, improve the permeability of concrete, frost resistance; 3, the strength of the concrete has been weakened, the size of the weakened and the amount of bubbles generated by the air entraining agent is related to the size of the bubbles, if the generated bubbles are mainly small holes, the weakening is relatively small. Of course, the water-reducing effect of air entraining agent will compensate the strength weakening caused by air entraining to some extent.
