Porous concrete based on red mud and Yellow River silt geopolymer and preparation method thereof
The invention provides porous concrete based on a red mud and Yellow River silt geopolymer and a preparation method of the porous concrete, and belongs to the technical field of concrete materials. The geopolymer cementing material comprises the following raw materials in percentage by mass: 10-40% of Yellow River silt, red mud and blast furnace slag, the geopolymer cementing material is used as a cementing material and is mixed with an alkali activator, aggregate and water to prepare porous concrete, and the porous concrete is cured at 90 DEG C. The strength of the geopolymer cementing material is mainly derived from C-A-S-H gel, the geopolymer cementing material has good working performance and high compressive strength, and conversion of the gel is more facilitated in a high-temperature and high-humidity environment, so that the yield of the gel is increased, the compressive strength of the porous concrete is improved, and the service life of the porous concrete is prolonged. And the environment-friendly porous concrete is prepared on the basis.
本发明提出了一种基于赤泥与黄河粉砂地聚合物的多孔混凝土及其制备方法，属于混凝土材料技术领域。本发明的地聚合物胶凝材料原料包括黄河粉砂、赤泥和高炉矿渣，按质量百分比计，所述黄河粉砂的用量为10％‑40％，并以该地聚合物胶凝材料为胶凝材料，与碱激发剂、骨料和水混合制备得到多孔混凝土，并在90℃条件下进行养护。本发明的地聚合物胶凝材料的强度主要来源于C‑A‑S‑H凝胶，具有良好工作性能且较高抗压强度，高温高湿环境更有利于凝胶的转化，从而增加了凝胶的产量，提高了多孔混凝土的抗压强度，并在此基础上制备出了具有环境友好型的多孔混凝土。
