Product Description:

Pumping Agent(high strength)JF-8

Description & Applications

  • *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

    and improve.

Pumping Agent High Strength JF-8 Construction Additive

Properties

  • *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.
