    Detail

    Applications

    VF-8 is used in concrete in industrial and civil buildings, hydraulic engineering, transport system, oil well drilling engineering, port engineering, and municipal engineering.

    VF-8 is used in ready mix plants, precast and prestressed concrete plants.

    VF-8 is especially for pumping concrete, as-cast-finish concrete, decorative concrete, self-leveling mortar and concrete.

    VF-8 is suit for concrete with the requirements of high early strength, high fluidity.

    VF-8 can be directly used with gypsum to improve the products performance.

    VF-8 is used in amorphous refractory cast materials.

    When VF-8 is mixed with gypsum plaster powder(mixing content is 0.3-1%).

    It can obviously decrease much water,and improve gypsum slurry plastic viscosity.

    It can improve the surface finish,durability,abrasion resistance of the gypsum products.Properties

    Excellent water-reducing ability.

    Enhance physical, mechanical and durability properties of concrete.

    High early strength, free bleeding and low air-entraining and low shrinkage.

    Excellent compatibility with sulphoaluminate and calcium aluminate cement.

    Packaging, transport and storage

    liquid VF-8 is available in sealed plastic or iron tank. Other special package can also be available according to prior consultation.

    The storage temperature should not be less than 0℃.

    Quality guarantee of VF-8 is 12 months under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
