Foam concrete reactive barrier material as well as preparation method and application thereof
The invention discloses a foam concrete reactive barrier material as well as a preparation method and application thereof, and belongs to the technical field of building materials. The foam concrete reactive barrier material is prepared by the following method: mixing a foaming agent with a small amount of nanoparticles, and then dissolving in water to prepare a foaming solution; mixing slag powder, porous fly ash, cement, modified red mud, biochar and nanoparticles, stirring, then adding a mixed solution of water and a chemical activator, and uniformly stirring to form gelled slurry; placing the foaming liquid in a foaming machine to generate foams, adding the foams into the gelling slurry, and uniformly stirring to obtain the foam concrete reactive barrier material. The foam concrete reactive barrier material prepared by the invention can remarkably remove heavy metal ions in sewage, and further has the advantages of good fluidity, high stability, high strength and the like, so that the foam concrete reactive barrier material can be well applied to mine filling and has important significance on environmental protection.
本发明公开了一种泡沫混凝土反应墙材料、其制备方法及应用，属于建筑材料技术领域。所述泡沫混凝土反应墙材料由如下方法制备而成：将发泡剂与少量纳米颗粒混合，然后溶解于水中，制备发泡液；将矿渣粉、多孔粉煤灰、水泥、改性赤泥、生物炭与纳米颗粒混合，搅拌，然后加入水与化学激发剂的混合液，搅拌均匀形成胶凝浆体；将发泡液置于发泡机中生成泡沫，并加至胶凝浆体中搅拌均匀，制得泡沫混凝土反应墙材料。本发明制备的泡沫混凝土反应墙材料，能够显著去除污水中的重金属离子，此外，该材料还具有流动度好、稳定性高以及强度高等优点，从而可在矿山充填中实现较好应用，对环境保护具有重要意义。
