The invention discloses concrete with fire resistance, and relates to the technical field of building materials. The concrete is prepared from the following raw materials: 180 to 260 parts of cement, 120 to 150 parts of water, 30 to 60 parts of waste steel fiber, 20 to 35 parts of fly ash, 20 to 30 parts of magnesia, 10 to 15 parts of a reinforcing agent, 6 to 8 parts of a polycarboxylic acid type water reducing agent and 1 to 5 parts of a dispersing agent. The preparation method comprises the following steps: (1) preparing the cement, the water, the waste steel fibers, the fly ash, the magnesia, the reinforcing agent, the polycarboxylic acid type water reducing agent and the dispersing agent; (2) transferring the raw materials in the step (1) into a stirrer, stirring and mixing, and pouring into a mold; and (3) curing the concrete in the mold in the step (2). The raw material components of the concrete are optimally configured, especially the reinforcing agent is introduced, and the fire resistance of the concrete can be effectively improved through tests.
本发明公开了一种具有耐火性能的混凝土，涉及建筑材料技术领域。混凝土的原料如下：水泥：180份‑260份，水：120份‑150份，废旧钢纤维：30份‑60份，粉煤灰：20份‑35份，镁砂：20份‑30份，增强剂：10份‑15份，聚羧酸系减水剂：6份‑8份，分散剂：1份‑5份；其制备方法如下：(1)准备水泥、水、废旧钢纤维、粉煤灰、镁砂、增强剂、聚羧酸系减水剂、分散剂；(2)步骤(1)中各原料转移到搅拌机中进行搅拌混合，并倒入模具中；(3)对步骤(2)模具中的混凝土进行养护。对混凝土的各原料组分进行了优化配置，尤其是引入了增强剂，经测试，可以有效提升混凝土的耐火性能。
