High-temperature-resistant 3D-printing fiber concrete with steel slag waste as aggregate, and preparation method of high-temperature-resistant 3D-printing fiber concrete
The invention discloses high-temperature-resistant 3D-printing fiber concrete with steel slag waste as aggregate and a preparation method of the high-temperature-resistant 3D-printing fiber concrete. The high-temperature-resistant 3D-printing fiber concrete comprises the following raw materials: cement, silica fume, fly ash, mineral powder, steel slag waste, nanoparticles, steel fibers, polypropylene fibers, a water reducing agent, a water-retaining agent and water. The high-temperature-resistant 3D-printing fiber concrete using the steel slag waste as the aggregate can meet the supply and demand of 3D printing, and has the characteristics of high strength, high toughness, high temperature resistance and the like. In addition, the prepared 3D printing fiber concrete uses the steel slag waste as the aggregate, so the utilization rate of solid waste is improved, and requirements for greenness and environmental protection are met.
本发明公开了一种以钢渣废料为骨料的耐高温3D打印纤维混凝土及其制备方法，该耐高温3D打印纤维混凝土，包括以下原料：水泥、硅灰、粉煤灰、矿粉、钢渣废料、纳米颗粒、钢纤维、聚丙烯纤维、减水剂、保水剂和水。本发明所得以钢渣废料为骨料的耐高温3D打印纤维混凝土不但能够满足3D打印的供需求，同时具备高强高韧性耐高温等特点。另外，本发明制备的3D打印纤维混凝土使用了钢渣废料作为骨料，提高固废利用，符合绿色环保的需求。
