Fiber concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to a preparation method of fiber concrete. The preparation method comprises the following steps: 1, performing strong acid soaking treatment on plant fibers, then performing strong alkali soaking treatment, and performing shearing and drying to obtain pretreated fibers; 2, the pretreated fibers are weighed and soaked in a water-retaining agent, stirring is conducted for 1-1.5 h, then an antioxidant is added, uniform mixing, heating and stirring are conducted, and modified plant fibers are obtained; 3, the recycled aggregate, the water reducing agent, the inorganic filler, the defoaming agent, the cement, the water, the corrosion inhibitor and the surfactant are weighed and evenly mixed with the modified plant fibers, stirring is conducted for 40-80 min, fiber concrete slurry is obtained, the fiber concrete slurry is poured into a mold to be fixed and formed, and the fiber concrete is obtained and has the good anti-cracking effect.
本申请涉及混凝土的技术领域，更具体地说，它涉及一种纤维混凝土的制备方法。步骤1：将植物纤维进行浸强酸处理，再进行浸强碱处理，剪切，烘干，得到预处理纤维；步骤2：称取预处理纤维浸没于保水剂中，搅拌1‑1.5h，再加入抗氧化剂，混合均匀，加热，搅拌，得到改性植物纤维；步骤3：称取再生骨料、减水剂、无机填料、消泡剂、水泥、水、缓蚀剂以及表面活性剂，与改性植物纤维混合均匀，搅拌40‑80min，得到纤维混凝土浆料，将纤维混凝土浆料浇筑于模具中固定成型，得到纤维混凝土，该纤维混凝土具有较好的抗裂效果。
