Synthetic fiber concrete and preparation method thereof
The invention discloses synthetic fiber concrete and a preparation method thereof.The synthetic fiber concrete is doped with 0.9-2.0 kg/m3 of synthetic fiber, and the synthetic fiber comprises a fiber trunk and fiber branches arranged at intervals in the length direction of the fiber trunk. The diameter of the fiber trunk is 2-10 times that of the fiber branches, and the length of the fiber trunk is 3.1-3.4 times that of the fiber branches. The bending toughness of the concrete can meet certain requirements under the condition that 0.9 kg/m3 of synthetic fibers are doped only by changing the shape and structure of the fibers doped into the concrete without adding other dispersing agents with a dispersing effect.
本申请公开一种合成纤维混凝土及其制备方法，所述合成纤维混凝土中掺入0.9‑2.0kg/m3的合成纤维，其中，所述合成纤维包括纤维主干，以及，沿所述纤维主干的长度方向间隔排布的纤维枝干。所述纤维主干的直径为所述纤维枝干的2‑10倍，所述纤维主干的长度为所述纤维枝干的3.1‑3.4倍。本申请仅通过改变掺入混凝土中纤维的形状构造，而无需添加其他具有分散作用的分散剂，即可在掺入0.9kg/m3的合成纤维的条件下，使混凝土的弯曲韧性满足一定要求。
