Water proof anti-cracking admixture JF-13

*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

*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.

Conclusion: the project is in line with acceptable end product index of “Water-repellent admixture” in JC474-2008.

*JF-13 is available in sealed plastic or iron tank. Other special package can also be available according to prior consultation.
*Quality guarantee of JF-13 is two year under normal conditions. If storage has surpassed thetime, test must be done to confirm the validity.
