Concrete doped with bunchy stranded basalt fibers and preparation method thereof
The invention discloses bunchy twisted basalt fiber composite concrete which is composed of a binding material, aggregate, an additive, bunchy twisted basalt fibers and water, and the fibers are the bunchy twisted basalt fibers; the preparation method of the composite concrete comprises the following steps: mixing fibers with quartz sand, mixing water, cement, fly ash, silica fume, slag, metakaolin, nano SO2, floating beads and a water reducing agent, and carrying out pouring molding, so as to obtain the bunchy twisted basalt fiber composite concrete. According to the prepared composite concrete, the bunchy stranded basalt fiber with the special-shaped surface is added, the uniform dispersion of the bunchy stranded basalt fiber in the concrete is realized by uniformly adding the fiber for multiple times and stirring for multiple steps, and the obtained concrete has good low contractibility, good durability, high strength, excellent toughness and wide application prospects.
本发明公开了一种束状绞联玄武岩纤维复合混凝土，所述混凝土由胶凝材料，骨料，外加剂，束状绞联玄武岩纤维和水组成，所述纤维为束状绞联玄武岩纤维；本发明所述复合混凝土的制备方法，将纤维与石英砂、拌合水、水泥、粉煤灰、硅灰、矿渣、偏高岭土、纳米SO2、漂珠、减水剂混合拌制，浇筑成型，即得到所述束状绞联玄武岩纤维复合混凝土；制得的复合混凝土，通过加入表面异形的束状绞联玄武岩纤维，并利用均匀多次加入纤维及多步搅拌，实现了束状绞联玄武岩纤维在混凝土中的均匀分散，所得混凝土具有良好的低收缩性，耐久性好，强度高，韧性优异，应用前景广阔。
