Star-shaped branched fiber, star-shaped branched fiber reinforced concrete and preparation method of star-shaped branched fiber reinforced concrete
The invention belongs to the technical field of building materials, and particularly designs a star-shaped branched fiber, star-shaped branched fiber reinforced concrete and a preparation method. The star-shaped branched fiber comprises a main branch and a plurality of auxiliary branches; a plurality of nodes connected with the auxiliary branches are arranged along the length direction of the main branches; a single auxiliary branch or a plurality of auxiliary branches are arranged on each node, so that a multi-point multi-branch star-shaped branched fiber or a multi-point single-branch star-shaped branched fiber is formed. The star-shaped branched fiber reinforced concrete is prepared from the following components in parts by weight: 900-1200 parts of a cementing material; 900 to 1200 parts of aggregate; 180 to 190 parts of water; 60 to 70 parts of fiber; the fiber special for the concrete with the star-shaped branched structure accounts for 10%-100% of the fiber content; and 10-15 parts of a water reducing agent. By adding the star-shaped branched fibers, the tensile capacity of the concrete is improved, the multi-axis tensile property of the oriented fiber concrete is improved, the characteristic that the multi-axis tensile capacity of the oriented fiber concrete is poor is improved, and the oriented fiber concrete has the characteristics of good bending impact resistance, corrosion resistance and high durability.
本发明属于建筑材料技术领域，尤其是设计一种星型支化纤维、星型支化纤维增强混凝土及制备方法。星型支化纤维包括主枝及多个副枝；沿主枝长度方向设有多个与副枝相接的节点；每个节点上设有单枝副枝或多枝副枝，形成多点多枝星型支化纤维或多点单枝的星型支化纤维。星型支化纤维增强混凝土由胶凝材料900‑1200份；集料900‑1200份；水180‑190份；纤维60‑70份；星型支化结构的混凝土专用纤维占纤维含量的10%‑100%；减水剂10‑15份制备；星型支化纤维的加入有利于提高混凝土抗拉能力，提高定向纤维混凝土多轴受拉性能、改善定向纤维混凝土多轴抗拉能力差的特点，具有抗弯冲击性能好、耐腐蚀和耐久性强的特点。
