Waste incineration fly ash-based high belite sulphoaluminate cement clinker and preparation method thereof
The invention belongs to the technical field of building materials, and provides a waste incineration fly ash-based high belite sulphoaluminate cement clinker and a preparation method thereof. The clinker is prepared from the following raw materials in parts by mass: 32.25 to 34.25 parts of waste incineration fly ash, 41.34 to 43.34 parts of carbide slag, 0.36 to 2.36 parts of ferric oxide and 22.05 to 24.05 parts of bauxite tailings. According to the method, the waste incineration fly ash serves as a preparation raw material, the fly ash contains high-content calcium sulfate and heavy metal ions, the components enter C2S mineral lattices in the calcination process, lattice distortion is caused, and the activity of C2S is improved. Meanwhile, heavy metal ions in the fly ash are effectively solidified in a clinker mineral structure, the leaching risk of heavy metal and environmental pollution are reduced, and harmless treatment of the fly ash is achieved. The waste incineration fly ash based high belite sulphoaluminate cement clinker prepared by the preparation method disclosed by the invention has excellent early compressive strength.
本发明属于建筑材料技术领域，提供了一种垃圾焚烧飞灰基高贝利特硫铝酸盐水泥熟料及其制备方法。该熟料包含下列质量份数的制备原料：垃圾焚烧飞灰32.25～34.25份、电石渣41.34～43.34份、三氧化二铁0.36～2.36份和铝土矿尾矿22.05～24.05份。本发明通过将垃圾焚烧飞灰作为制备原料，飞灰中具有高含量硫酸钙及重金属离子，煅烧过程中这些成分进入C2S矿物晶格，导致晶格畸变，提高了C2S的活性。同时，飞灰中的重金属离子被有效固化在熟料矿物结构中，减少了重金属的浸出风险和环境污染，实现了飞灰的无害化处理。本发明制备得到的垃圾焚烧飞灰基高贝利特硫铝酸盐水泥熟料具有优异的早期抗压强度。
