Application of fiber in UHPC (Ultra High Performance Concrete)
The invention discloses application of fiber in UHPC (Ultra High Performance Concrete). The fiber comprises a polymer matrix, a fiber material, a carbon black nano material, an antioxidant, water, a coupling agent, a dispersing agent, a catalyst and a filler. By adding the fiber material, the compressive strength, the tensile strength and the bending strength of the concrete can be improved, meanwhile, the toughness and the ductility of the concrete are improved, and the concrete has better crack resistance. The fiber reinforced material can effectively reduce capillary pores of the concrete, reduce the permeability of the concrete and improve the impermeability of the concrete. By adding the fiber material, the impact resistance and fatigue resistance of the concrete can be improved, so that the concrete has better stability when being impacted or vibrated. The fiber material forms a uniformly-distributed network structure in the concrete, and when cracks are generated, the fibers can prevent the cracks from expanding, so that the influence of the cracks on the concrete structure is reduced.
本发明公开了一种纤维在UHPC混凝土中的应用，包括聚合物基体、纤维材料、炭黑纳米材料、抗氧剂、水、偶联剂、分散剂、催化剂、填料。本发明中纤维材料的加入有助于提高混凝土的抗压强度、抗拉强度和抗弯强度，同时提高混凝土的韧性和延性，使混凝土具有更好的抗裂性能。纤维增强材料能够有效减少混凝土的毛细孔，降低混凝土的渗透性，提高混凝土的抗渗性能。本发明纤维材料的加入可以提高混凝土的抗冲击性能和抗疲劳性能，使混凝土在受到冲击或振动时具有更好的稳定性。纤维材料在混凝土中形成均匀分布的网络结构，当裂缝产生时，纤维可以阻止裂缝的扩展，减轻裂缝对混凝土结构的影响。
