UHPC Special Synthetic Fibre
Product Description
UHPC special synthetic fiber uses hydrophilic modification technology for its surface treatment.
UHPC fiber products are 40 denier, monofilament PVA fibers for use in fiber reinforced concrete, stucco, shotcrete and precast. UHPC Fiber is
specifically designed for use in concrete products for the purpose of controlling plastic shrinkage, thermal cracking and improving abrasion resistance.
It has excellent dispersibility in UHPC, and has good bonding performance with cement matrix materials, which can effectively reduce and inhibit UHPC plastic shrinkage, drying shrinkage, Micro-cracks caused by temperature changes and other factors significantly improve crack resistance, toughening , impact resistance, fire and explosion resistance of UHPC.
It can be used in all types of concrete. Synthetic fibers help the concrete at early ages, which is especially beneficial where stripping time and handling is important.

Guidelines for use
Dosage: the usual dosing amount is 5.0-50.0kg /m3( the corresponding volume dosing amount is 0.4-4.0%).
Length: The length of UHPC should be 6-12mm. According to different thicknedd of components.
Stirring: After mixing the UHPC powder and water to make the slurry evenly, add the fibers, and then stir for 2 to 4 minutes, subject to the
uniform dispersion of the fibers.
Curing: The construction and curing process of UHPC after adding fiber is exactly the same as the system without fiber
