Cement-free waste incineration slag-based baking-free brick and preparation method thereof
The invention relates to the technical field of resource utilization of waste incineration slag, and particularly discloses a cement-free waste incineration slag-based baking-free brick and a preparation method thereof. The cement-free waste incineration slag-based baking-free brick comprises the following components in parts by mass: 6-8 parts of waste incineration slag, 2-4 parts of an admixture and 3-5 parts of an alkali activator. The preparation method of the cement-free waste incineration slag-based baking-free brick comprises the steps of a, grinding the waste incineration slag, and uniformly mixing the ground waste incineration slag with the admixture and the alkali activator to obtain a semi-dry material; b, adding the semi-dry material into a mold for compression molding to obtain a molded test block; and c, curing the molded test block to obtain the baking-free brick. The cement-free waste incineration slag-based baking-free brick provided by the invention has the advantages of simple materials, low cost, high use strength, good curing effect of heavy metal elements, difficulty in leaching and large-scale popularization and application.
本发明涉及垃圾焚烧炉渣资源化利用技术领域，具体公开一种无水泥的垃圾焚烧炉渣基免烧砖及其制备方法。所述无水泥的垃圾焚烧炉渣基免烧砖包括以下质量份数的成分：垃圾焚烧炉渣6‑8份，掺合料2‑4份和碱激发剂3‑5份，其制备方法包括：a、将所述垃圾焚烧炉渣粉磨后与掺合料和碱激发剂混合均匀，得到半干料；b、将所述半干料加入模具中压制成型，得到成型试块；c、对所述成型试块进行养护，得到所述免烧砖。本发明提供的无水泥的垃圾焚烧炉渣基免烧砖具有用料简单、成本低、使用强度高、重金属元素固化效果好不易浸出以及可以大规模推广使用的优势。
