    Detail

    Applications

    JF-6 improves the early strength and later strength of concrete in the environment of alternating temperatures..

    JF-6 is the major measures for speeding up the job scheduler and improving work efficiency.

    JF-6 applies to the project of precast concrete, cast-in-place concrete, steam-cured concrete and early strength concrete.

    Properties

    Dosage: 1.5-2.5%, water-reducing rate: 10-15%.

    JF-6 can save cement 10-15% and don’t decrease the strength, when it is circumstanced under the same slump constant.

    JF-6 isn’t suitable for the steamed curing

    Strength of JF-6 increases quickly.

    JF-6 applies to concrete work under the condition of -5℃-30℃.

    Packaging, transport and storage

    Powder JF-6 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-6 is two year under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
