Steel fiber concrete
The invention discloses steel fiber reinforced concrete, and belongs to the technical field of ultra-high performance concrete materials. The concrete is prepared from the following raw materials in parts by weight: 400-450 parts of cement, 300-400 parts of sand, 600-800 parts of gravel, 60-70 parts of fly ash, 10-15 parts of silica fume, 80-100 parts of water, 10-20 parts of modified steel fibers, 3-7 parts of polypropylene fibers, 3-5 parts of a water reducing agent, 1-3 parts of a corrosion inhibitor and 0.5-1 part of an anti-freezing agent. The cement, the silica fume, the fly ash, the river sand, the gravel and other raw materials are scientifically proportioned, the concrete is good in workability and cohesiveness, the steel fibers are modified by using the silane coupling agent with gradient concentration, the adhesive force between the steel fibers and a cement matrix is greatly improved, agglomeration is reduced, meanwhile, the corrosion resistance of the concrete is improved, the service life is prolonged, and the concrete is suitable for large-scale production. And additives such as a corrosion inhibitor and an anti-freezing agent are added, so that the adaptability and stability of the concrete are improved, the application field is widened, and the economic value is improved.
本发明公开钢纤维混凝土，属于超高性能混凝土材料技术领域。混凝土包括以下重量份的原料制备而成：水泥400‑450份、砂300‑400份、碎石600‑800份、粉煤灰60‑70份、硅灰10‑15份、水80‑100份、改性钢纤维10‑20份、聚丙烯纤维3‑7份、减水剂3‑5份、阻锈剂1‑3份、防冻剂0.5‑1份。本发明科学配比水泥、硅灰、粉煤灰、河砂、碎石等原料，混凝土和易性好，粘聚性好，利用梯度浓度的硅烷偶联剂对钢纤维进行改性，大幅提升钢纤维与水泥基体的附着力，减少团聚，同时提升混凝土的防腐蚀能力，延长使用寿命，添加阻锈剂、防冻剂等外加剂，提升混凝土的适应性和稳定性，拓宽应用领域，提升经济价值。
