High-performance fiber concrete and preparation method thereof
The invention discloses high-performance fiber concrete which comprises the following components in parts by weight: 70 to 80 parts of ordinary Portland cement; 15 to 25 parts of fly ash; 200 to 230 parts of stone; 130 to 150 parts of sand; 35 to 45 parts of water; 3 to 6 parts of a water reducing agent; 0.2 to 0.4 part of basalt fiber; 0.3 to 0.4 part of PVA (Polyvinyl Alcohol) fiber; and 1 to 2 parts of nano silicon dioxide. According to the high-performance fiber concrete and the preparation method thereof, the basalt fibers and the PVA fibers are loaded into the concrete, so that the concrete is not prone to cracking, the crack resistance of the concrete is greatly improved, meanwhile, the overall strength and compressive strength are greatly improved, the strength, durability and crack resistance of the concrete are improved, the compressive strength can reach 111 MPa, the application range is wide, and the concrete can be used in special concrete structures.
本发明公开了一种高性能纤维混凝土，包括如下重量份数的组分:普通硅酸盐水泥：70～80份；粉煤灰：15～25份；石子：200～230份；砂子：130～150份；水：35～45份；减水剂：3‑6份；玄武岩纤维：0.2～0.4份；PVA纤维：0.3～0.4份；纳米二氧化硅：1～2份。该高性能纤维混凝土及其制备方法，通过设置的玄武岩纤维和PVA纤维填充到混凝土中，使得混凝土不易发生开裂现象，极大的提高了混凝土的抗裂性，同时，整体的强度和抗压强度均得到大幅度的提升，提高了混凝土的强度、耐久性及抗裂性，抗压强度可达到110.MPa，应用范围广泛，可用于特种混凝土结构中。
