Product Description:

Pumping Agent  Concrete Admixture JF-9 Construction Chemical Additive

Description:

It's a brown liquid.It can prevent concrete from being isolated or blocked in the pumping pipeline, thus improving its pumping peformance. This product complies with the national standard of first class concrete pumping agent in building material industry.


Applications


  • *JF-9 is divided into powder and liquid.

  • *JF-9 is suitable for transporting goods concrete at long bowls and pumping on the scene.

  • *JF-9 has the effect of delayed coagulation, when it mixed use with other admixture,

    test must be done to confirm the validity.

  • *When JF-9 is first use, it must be mixed according to above introduction in the testing laboratory.

  • Properties:

    • *Dosage: 1.4~2.4%, water-reducing rate: 13-26%.

    • *The same cement water ratio with JF-9 can improve incipient slump constant of concrete 10cm above,and it is

      suitable for transporting goods concrete at long bowls.

    • *Greatly improved the workability、moisture retention、cohesiveness of JF-9,  and can reduce pipeline pressure

      when pump.

    • *There is delayed coagulation in initial set, can reduce the early rate of exothermic reaction during hydration

      and be favorable to pour concrete in mass.

    • *To improve and change the pressive strength、rupture strength、tensile-strength、impermeability、lasting

      quality of concrete.

    • *JF-9 applies to concrete work under the condition of -5℃-40℃.
