Geopolymer concrete based on household garbage incinerator slag and red mud and preparation method thereof
The invention discloses geopolymer concrete based on household garbage incineration slag and red mud and a preparation method of the geopolymer concrete, and the preparation method comprises the following steps: respectively carrying out first pretreatment on the household garbage incineration slag and the red mud to obtain first pretreated slag and first pretreated red mud, then carrying out second pretreatment to obtain second pretreated slag and second pretreated red mud, uniformly mixing the first pretreated furnace slag, the first pretreated red mud and the municipal dewatered sludge, granulating to obtain a green body, drying the green body, then carrying out first heating, then cooling to obtain porous lightweight aggregate ceramsite, carrying out second heating on the second pretreated red mud, then cooling so that modified red mud is obtained, uniformly mixing the second pretreated furnace slag, the modified red mud and an alkali activator to obtain geopolymer powder, adding water into the geopolymer powder, uniformly mixing, adding the porous lightweight aggregate ceramsite, and uniformly mixing to obtain the geopolymer concrete. The utilization rate of red mud, waste incineration slag and municipal sludge can be increased, and environmental pollution is reduced.
本发明公开了一种基于生活垃圾焚烧炉渣和赤泥的地聚合物混凝土及其制备方法，将生活垃圾焚烧炉渣和赤泥分别进行第一预处理，获得第一预处理炉渣和第一预处理赤泥，后进行第二预处理，获得第二预处理炉渣和第二预处理赤泥；将所述第一预处理炉渣、所述第一预处理赤泥和所述市政脱水污泥混匀后进行造粒，获得生坯；将所述生坯干燥，后进行第一加热，后冷却，获得多孔轻骨料陶粒；将所述第二预处理赤泥进行第二加热，后冷却，获得改性赤泥；将所述第二预处理炉渣、所述改性赤泥和碱活化剂混匀，获得地聚合物粉末；将所述地聚合物粉末加水后混匀，后加入所述多孔轻骨料陶粒混匀，获得地聚合物混凝土。本发明可提高赤泥、垃圾焚烧炉渣、市政污泥的利用率，减少环境污染。
