Concrete containing steel slag and preparation method thereof
The invention relates to the field of concrete, and particularly discloses concrete containing steel slag and a preparation method thereof. The concrete is prepared from the following raw materials in parts by weight: 240 to 252 parts of cement, 155 to 165 parts of water, 55 to 65 parts of slag powder, 55 to 61 parts of fly ash, 50 to 60 parts of steel slag powder, 6.5 to 7.5 parts of water glass, 2.0 to 2.4 parts of basalt fiber, 780 to 820 parts of fine aggregate, 1015 to 1023 parts of coarse aggregate and 6.5 to 7.3 parts of additive, the preparation method comprises the step of mixing and stirring all the raw materials for 20-30 minutes under the conditions that the temperature is 20-25 DEG C and the rotating speed is 300-350r/min. The steel slag-containing concrete provided by the invention has the advantages of fewer pores, higher compactness, excellent mechanical properties, higher stability, low production cost and suitability for large-scale production, and the phenomena of cracking, bending, collapse and the like are not easy to generate.
本申请涉及混凝土领域，具体公开了一种含钢渣的混凝土及其制备方法。混凝土所用原料包括以下重量份的组分：水泥240‑252份、水155‑165份、矿渣粉55‑65份、粉煤灰55‑61份、钢渣粉50‑60份、水玻璃6.5‑7.5份、玄武岩纤维2.0‑2.4份、细骨料780‑820份、粗骨料1015‑1023份和外加剂6.5‑7.3份；其制备方法为：在温度为20‑25℃，转速为300‑350r/min的条件下，将所有原料混合搅拌20‑30min。本申请的含钢渣混凝土孔隙数量较少，密实程度较高，力学性能优异，安定性较高，不易产生裂缝、弯曲、崩塌等现象，且生产成本较低，适合大规模生产。
