*Quite obvious delayed coagulation before initial set, the strength develop continuously and steadily in middle and later
periods and in final set the strength increase quickly.
*Workability, impermeability, durability and each index of mechanical properties of concrete with JF-8 obviously increase
*Dosage: 0.75-1.5%, water-reducing rate: 15-30%.
*JF-8 can be cooperated to use with good quality of mineral admixture to make C80 high strength concrete.
*JF-8 can increase the value of slump constant: 10-15cm when the same water consumption
come within the range of suitable content.
*When JF-8 is used for mixing fluid concrete, the loss of slump constant is less than 3cm
within two hours, and it is suitable for transporting goods concrete at long bowls.
*JF-8 applies to concrete work under the condition of 5℃-40℃.
*When JF-8 mixed use with other admixture, test must be done to confirm the validity.

Conclusion: the project is in line with acceptable end product index of “pumping agent” in
JC473-2001 and the “pumping agent” index of GB8076-2008.
Remark: Experiment must be done when changing cement and aggregate type.
*Powder JF-8 is available in 25kg film-lined bags. Other special package can also
be available according to prior consultation.
*Special measures should be taken to ensure entire package. Keep waterproof during transportation.
*Dry and well ventilated warehouse is needed for storage. Quality guarantee of JF-8 is two year under
normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
