Ultra-high performance fiber reinforced concrete and preparation method thereof
The invention discloses ultrahigh-performance fiber reinforced concrete and a preparation method thereof. The ultrahigh-performance fiber reinforced concrete is mainly prepared from the following raw materials in parts by mass: 60-65 parts of cement, 15-36 parts of silica fume, 20-50 parts of fly ash, 20-25 parts of quartz powder, 45-55 parts of quartz sand, 4-8 parts of hybrid fibers, 1-2 parts of a water reducing agent and 20-100 parts of water. The hybrid fiber is mainly formed by mixing 2-4 parts of basalt fiber, 1-2 parts of PVA fiber and 1-2 parts of PE fiber; the basalt fibers are formed by mixing basalt fibers with different lengths. The ultrahigh-performance fiber reinforced concrete provided by the invention has excellent mechanical properties, and can be suitable for high-speed rail cable troughs and covers, pedestrian overpasses, light bridge decks, short rib plate composite beams, steel frame arch bridges, building exterior facing, repairing and reinforcing structures and the like for a long time.
本发明公开了一种超高性能纤维增强混凝土及其制备方法，主要由下述质量份的原料制成：水泥60～65份、硅灰15～36份、粉煤灰20～50份、石英粉20～25份、石英砂45～55份、混杂纤维4～8份、减水剂1～2份、水20～100份；所述混杂纤维主要由玄武岩纤维2～4份、PVA纤维1～2份和PE纤维1～2份混杂而成；所述玄武岩纤维为不同长度的玄武岩纤维混杂。本发明提供的超高性能纤维增强混凝土具备优良的力学性能，能够长期适用于高铁电缆槽和盖、人行天桥、轻质桥面板、矮肋板组合梁、钢架拱桥、建筑外饰面和修复加固结构等方面。
