Red mud/steel slag-based wave-absorbing cementing material and preparation method thereof
The invention belongs to the field of comprehensive utilization of solid waste resources, and provides a red mud/steel slag-based wave-absorbing cementing material and a preparation method of the red mud/steel slag-based wave-absorbing cementing material. The red mud/steel slag-based wave-absorbing cementing material is prepared from the following raw materials in parts by weight: 300-400 parts of steel slag, 100 to 140 parts of red mud; 3 to 5 parts of graphene; 40-60 parts of waste foam particles; 30-50 parts of a reinforcing agent; 15 to 20 parts of a water reducing agent; and 120 to 160 parts of mixing water. The preparation method comprises the following steps: firstly, adding the graphene and the water reducing agent into the mixing water, and treating in a 340W ultrasonic environment for 4 minutes to form a uniform graphene aqueous solution; secondly, steel slag, red mud, waste foam particles and a reinforcing agent are added into a stirring pot to be evenly stirred, then the graphene aqueous solution is added to be evenly stirred, and prepared slurry is poured into a mold; and finally, maintaining the sample in an air environment, and removing the mold. The red mud/steel slag based wave-absorbing cementing material prepared by the invention not only has relatively low production cost, but also has relatively good electromagnetic wave absorbing performance, is beneficial to promoting comprehensive utilization of industrial source solid waste resources such as the steel slag and the red mud, and has remarkable environment-friendly, economic and engineering application values.
本发明属于固废资源综合利用领域，提供一种赤泥/钢渣基吸波胶凝材料及制备方法，其原材料为：钢渣300‑400份；赤泥100‑140份；石墨烯3‑5份；废弃泡沫颗粒40‑60份；增强剂30‑50份；减水剂15‑20份；拌合水120‑160份。制备方法为：首先，将石墨烯、减水剂加入拌合水中，置于340W超声波环境中处理4min，形成均匀的石墨烯水溶液；其次，将钢渣、赤泥、废弃泡沫颗粒、增强剂加入至搅拌锅中搅拌均匀，再加入石墨烯水溶液搅拌均匀，将制备的浆体浇注于模具中；最后，将试样在空气环境中养护后拆模。本发明制备的赤泥/钢渣基吸波胶凝材料不仅具有较低的生产成本，还有较好的电磁波吸波性能，有利于推动工业源固废资源钢渣、赤泥的综合利用，具有显著的环保、经济及工程应用价值。
