Directional distribution fiber concrete member and preparation method thereof
The invention discloses a directionally-distributed fiber concrete member, the member comprises a fiber skeleton and concrete, the fiber skeleton is wrapped by the concrete, the concrete is composed of the following components in parts by weight: 62-65 parts of P.O52.5 cement, 15-26 parts of microbeads, 16-27 parts of blast furnace slag powder, 12-16 parts of silica fume, 90-120 parts of sand, 0.2-0.8 part of a water reducing agent and 27-32 parts of water, and the fiber skeleton is made of fibers. The fiber skeleton is manufactured through a finite element analysis method and a 3D printing, pouring or binding method, compared with a magnetic field regulation and control method, the types of fibers are not limited to magnetic materials any more, practicability is higher, the method is particularly suitable for prefabricated parts with stable loads, the utilization efficiency of the fibers in fiber concrete is effectively improved, and the manufacturing cost of the fiber skeleton is reduced. The strength, the ductility and the cracking resistance of the component are improved.
本发明公开了一种定向分布的纤维混凝土构件，构件包括纤维骨架和混凝土，混凝土包裹纤维骨架，所述混凝土以重量份数计，由以下成分组成：P·O52.5水泥62‑65份、微珠15‑26份、高炉矿渣粉16‑27份、硅灰12‑16份、砂90‑120份、减水剂0.2‑0.8份和水27‑32份，所述纤维骨架为纤维制作。本发明通过有限元分析的方法并通过3D打印、浇筑或者绑扎方法进行纤维骨架的制作，与磁场调控的方法相比，纤维的类型不再局限于磁性材料，且实用性更强，尤其适用于受荷稳定的预制构件，有效地提高了纤维混凝土中纤维的利用效率，提高了构件强度和延性以及抗开裂能力。
