Lightweight carbonized product based on cement kiln ash and preparation method thereof
The invention discloses a lightweight carbonized product based on cement kiln dust. The lightweight carbonized product is prepared from the following raw materials in parts by weight: 100 parts of kiln dust, 20-40 parts of fly ash, 4-8 parts of reinforced fibers, 10-30 parts of lightweight aggregate, 0.05-2 parts of a stabilizer and 0.2-0.8 part of a dispersing agent, the water-solid ratio is 0.4 to 0.6; wherein the lightweight aggregate is obtained by adding water into kiln dust and fly ash, rolling, granulating, aging, carbonizing and screening. The kiln dust can be harmlessly and resourcefully treated, carbon emission in the cement production process is reduced, and the energy utilization rate of the cement kiln is increased; the properties of light weight, high strength and the like can be considered; the preparation method and process are simple, have good economic benefits and environmental benefits, and are suitable for popularization and application.
本发明公开了一种基于水泥窑灰的轻质碳化制品，各原材料及其所占重量份数包括：窑灰100份，粉煤灰20～40份，增强纤维4～8份，轻质骨料10～30份，稳定剂0.05～2份，分散剂0.2～0.8份；水固比0.4～0.6；其中，轻质骨料利用窑灰和粉煤灰加水辊压造粒、陈化、碳化、筛分得到。本发明可无害化、资源化处置窑灰，减少水泥生产过程碳排放，提高水泥窑能源利用率；并可兼顾质轻、强度高等性能；且涉及的制备方法和工艺简单，具有良好的经济效益和环境效益，适合推广应用。
