Features of Air-entraining Agent:
1, After application,the small, uniform, stable, closed,independent bubble are generated,significant improvement on theproperties of anti-filtration and frost resistance. 2,packed withthe barrel, it remains effective in one year. After long time ofstorage time, little mixing needed to make it even, withoutsurrendering any effect.
3, No poisonous gradient.
4, The increase of the alkali is less than 0.1kg per ton ofconcrete (as 400kg cementitious materials).
Application :
widely used in the concrete with aim entraining requirement, suchas dam concrete, pavement concrete, construction in winterconcrete, anti-filtration concrete,high durability concrete.
Recommended Dosage
1. 0.01% -0.03% of the cementing material, change the dosageaccording to the air content of the concrete.
2. without negative effect to the cement below C40, testing shouldbe carried to determine the dosage of cement above C40 .
Instructions
Instructions :
1. Admixture must be accurately measured, preferably dilute100-fold, and then blend as the percentage of it.
2. When constructing, vibrate the concrete as evenly as possible,avoid excessive vibration and less vibration, make the bubblesevenly distributed.
3. Covered with lid when storing , avoid the change ofconcentration.
