Fiber reinforced concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses fiber reinforced concrete and a preparation method thereof. The fiber reinforced concrete is prepared from the following raw materials in parts by weight: 200 to 260 parts of cement, 800 to 1000 parts of modified aggregate, 100 to 140 parts of water, 5 to 10 parts of accelerator, 4 to 6 parts of water reducing agent, 10 to 18 parts of reinforced fiber and 10 to 20 parts of filler, the modified aggregate is prepared by coating the surface of the aggregate with hydrophobic titanium dioxide; the preparation method comprises the following steps: weighing the cement, the modified aggregate, the reinforced fibers and the filler, and uniformly mixing and stirring to obtain a primary mixture; weighing water, an accelerator and a water reducing agent, and uniformly mixing and stirring with the primary mixture to obtain a mixed material; and spraying and curing the mixture to obtain the finished product concrete. The surface of the slope protection concrete has good friction force, meanwhile, substances such as algae are not prone to being attached to the surface of the concrete, and therefore it is guaranteed that the concrete of the river channel slope protection still has high strength under the long-time use condition.
本申请涉及混凝土领域，具体公开了一种纤维增强混凝土及其制备方法；一种纤维增强混凝土包含以下重量份的原料制成：水泥200‑260份、改性骨料800‑1000份、水100‑140份、速凝剂5‑10份、减水剂4‑6份、增强纤维10‑18份、填料10‑20份；改性骨料由骨料表面包覆疏水二氧化钛制得；其制备方法为：称取水泥、改性骨料、增强纤维、填料混合搅拌均匀，制得初混料；称取水、速凝剂、减水剂与初混料混合搅拌均匀，制得拌和料；拌合料经喷射、养护，制得成品混凝土；使护坡混凝土表面具有较好摩擦力的同时使混凝土表面不易附着藻类等物质，从而保证河道护坡的混凝土在长时间使用条件下仍具有较高的强度。
