Fiber concrete as well as preparation method and application thereof
The invention relates to fiber concrete as well as a preparation method and application thereof. The fiber concrete is mainly prepared from the following raw materials in parts by weight: 470-740 parts of a gel material, 560-700 parts of fine aggregate, 17-75 parts of a fiber material and 2-8 parts of a nano material, the gel material is prepared from the following components in parts by weight: 400 to 550 parts of cement, 35 to 65 parts of silica fume and 35 to 125 parts of fly ash; the fine aggregate comprises the following components in parts by weight: 560-700 parts of sand; the fiber material comprises the following components in parts by weight: 2-15 parts of basalt fiber and 15-60 parts of steel fiber; the nano material comprises the following component: 2-8 parts of nano silicon dioxide. According to the fiber concrete disclosed by the invention, the drawing and bridging effects of the steel fibers and the basalt fibers are utilized, so that initiation and expansion of cracks of a cement matrix are effectively controlled, internal native defects are reduced, and the macroscopic mechanical property of the fiber concrete is improved.
本发明涉及一种纤维混凝土及其制备方法和应用。一种纤维混凝土，主要由以下重量份的原料制备而成：凝胶材料470～740份、细骨料560～700份、纤维材料17～75份、纳米材料2～8份；所述凝胶材料包括以下组分：水泥400～550份、硅灰35～65份、粉煤灰35～125份；所述细骨料包括以下组分：砂子560～700份；所述纤维材料包括以下组分：玄武岩纤维2～15份、钢纤维15～60份；所述纳米材料包括以下组分：纳米二氧化硅2～8份。本发明的纤维混凝土利用钢纤维和玄武岩纤维的拉拔和桥接效应，有效地控制水泥基体裂纹的萌生、扩展，减少内部原生缺陷，提高其宏观力学性能。
