Product Description:

Water proof anti-cracking admixture   JF-13

Applications

  • *JF-13 is liquid.

  • *JF-13 is suitable for concrete with impermeability and cracking resistance, and can be used  in conjunction with the fiber.

  • *JF-13 has tiny dilatability and can improve shrinkage of concrete effectively to reduce  concrete shrinkage and concrete cracking.

  • *JF-13 has the effect of delayed coagulation, when it mixed use with other admixture,  test must be done to confirm the validity.

  • *When JF-13 is first used, it must be mixed according to above introduction in the testing laboratory.


Water Proof Anti-Cracking Admixture  JF-13 Construction Chemicals

Properties


  • *Dosage: 1.6~2.4%, water-reducing rate: 13-26%.

  • *The same cement water ratio with JF-13 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-13, 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-13 applies to concrete work under the condition of -5℃-40℃.

  • *Impervious gradation of mortar can be P8-P10, impervious gradation of C30 concrete can be P14.  The highest impervious gradation of concrete can be P40.
