High-silicon low-carbon cement clinker prepared from waste incineration fly ash and preparation method of high-silicon low-carbon cement clinker
The invention belongs to the technical field of building materials, and discloses a high-silicon low-carbon cement clinker prepared from waste incineration fly ash and a preparation method of the high-silicon low-carbon cement clinker. The waste incineration fly ash high-silicon low-carbon cement clinker is prepared from the following raw materials in percentage by mass: 25 to 30 percent of waste incineration fly ash, 40 to 45 percent of desulfurization slag, 1 to 2 percent of ferric oxide, 22 to 25 percent of high-alumina coal gangue and 4 to 6 percent of gypsum. The invention aims to reduce the firing temperature of C4A3 by utilizing impurities in the waste incineration fly ash and optimizing the proportion and the calcining system, so that the C4A3 and C5S2 coexist at 1200 DEG C. And multiphase components in the fly ash, such as calcium sulfate and other trace elements, are beneficial to regulation and control of formation and stability of minerals, so that coexistence of C4A3 and C5S2at a relatively low temperature is realized, the overall performance of the cement clinker is improved, recycling and harmless treatment is realized, and remarkable economic and environmental benefits are achieved.
本发明属于建筑材料技术领域，公开了一种垃圾焚烧飞灰高硅型低碳水泥熟料及其制备方法。该垃圾焚烧飞灰高硅型低碳水泥熟料，包括以下质量百分比的制备原料：垃圾焚烧飞灰25～30％、脱硫渣40～45％、三氧化二铁1～2％、高铝煤矸石22～25％、石膏4～6％。本发明旨在利用垃圾焚烧飞灰中的杂质，通过优化配比和煅烧制度，降低C4A3$的烧成温度，使其与C5S2$在1200℃下共存。飞灰中的多相成分，如硫酸钙和其他微量元素，有助于调控矿物的形成和稳定性，从而实现C4A3$和C5S2$在较低温度下的共存，提高水泥熟料的整体性能，实现资源化和无害化处理，具有显著的经济和环境效益。
