    Detail

      Applications

      Impermeability mark of JF-3 can be P12, intensity of 100 times freezing and thawing cycle without loss and lasting quality has improved significantly.

      JF-3 is suitable for continuous concrete in mass in the hot season, reduce the hydration heat and avoid temperature cracks.

      JF-3 can improve the concrete workability and enhance the technical performance of concrete.

      To strictly control the content in accordance with the mix ratio of construction, do not exceedthe recommended dosage.

      Before JF-3 mixed use with other admixture, it must pass the laboratory test.it can be mixed with other water to get good effect.

      JF-3 is chloride – free, low alkali, good for the adaptability of cement and can be used in all kinds of reinforced concrete engineering.

      JF-3 is applicable to concrete construction in the temperature conditions of - 5 ° c - 40 degrees Celsius.

      JF-3 isn’t suitable for the cement admixture which is made by anhydrite and fluorgypsum and also unsuitable for prefabricated part of steam curing.

      Properties

      Excellent water-reducing ability. JF-3 can significantly reduce 15% ~30% mixing water in concrete with 1.5%~3.0% dosage.

      JF-3 can be cooperated to use with good quality of mineral admixture to make C80 high strength concrete.

      Setting time: setting time delay 2-4h.Raise special requirements in the service at pre-sales stage.

      Packaging, transport and storage

      Liquid JF-3 is available in sealed plastic or iron tank. 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-3 is two year under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
