JF-5 is no chlorine and low alkali.
JF-5 is low content, reasonable price and better economic result.
JF-5 applies to common concrete.
JF-5 applies to the cement admixture which is made by anhydrite and fluorgypsum and steamed concrete
Dosage: 0.5-1.0%.
There was no significant effect on the setting time.
Air content increased slightly.
Retention value of slump constant: 1h≥90%
Before JF-5 mixed use with other admixture, it must pass the laboratory test.
Use it in the above 5 degrees celsius temperature conditions.

Conclusion: the project is in line with retarding index of “water-reducing admixture” of GB8076-2008.
Powder JF-5 is available in 25kg film-lined bags. Other special package can also be available according to prior
consultation.
Dry and well ventilated warehouse is needed for storage to prevent absorption of moisture and agglomeration.
If storage has surpassed the time, test must be done to confirm the validity.
