The surface of UHPC special polypropylene macro fiber is treated by hydrophilic modification technology. It has excellent dispersibility in UHPC and good bonding performance with cement matrix material. It can effectively reduce and inhibit the micro cracks caused by plastic shrinkage, drying shrinkage, temperature change and other factors of UHPC, and significantly improve the crack resistance, toughening, impact resistance, fire and explosion resistance of UHPC.
