Sodium Dodecyl Benzene Sulfonate
LAS-70
Chemical Nature
Sodium dodecyl benzene sulfonate is a kind of air entraining agent, which is dissolved in water and added to the concrete mixture, and can produce a lot of tiny bubbles during the mixing process. Air entrainment agent can improve the workability, water retention and cohesiveness of concrete mixture and increase the fluidity of concrete.
Features of application
1, 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.
Storage
The product should be stored in a dry, clean environment, in its original packaging and away from heat sources. This product is not easy to fail, but it is a hydrophilic product, if the storage environment is poor, it will slowly inhale water, it is recommended to follow the principle of first in first out when using. If the product is not used up, the packaging must be tightly sealed to prevent moisture intrusion.
