    Detail

    Applications

    VF-15 is suitable for winter construction of all kinds of concrete at the average temperature of -5 ℃ -15 ℃.

    Slump loss of VF-15 is small.

    VF-15 has better applicability for all kinds of cement and composite material.

    VF-15 is chloride – free, low alkali and hazardous substance.

    VF-15 hasn’t corrosion for reinforcement metal.

    VF-15 belongs to green production.

    Properties

    Dosage: 2.5~4.5% at temperatures not lower than -15 ℃.

    Mixing water should be required to heat.

    Pumping's temperature of concrete should be higher than 5 ℃ and use comprehensive thermal storage method.

    None

    Remark: set point of temperature is -10℃(serviceability temperature is -15℃)

    Conclusion: the project is in line with acceptable end product index in JC475-2004.

    Packaging, Transport and Storage

    VF-15 is available in metal pail or iron tank. Other special package can also be available according to prior consultation.

    VF-15 must be stored at the temperature above 0℃. Special measures should be taken to ensure entire package.

    Dry and well ventilated warehouse is needed for storage. Quality guarantee of VF-15 is one year under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
