Phosphogypsum-based waste incineration fly ash composite cementing material as well as preparation method and application thereof
The invention provides an ardealite-based waste incineration fly ash composite cementing material as well as a preparation method and application thereof, and belongs to the fields of comprehensive utilization of ardealite and waste incineration fly ash and building materials. The invention provides a phosphogypsum-based waste incineration fly ash composite cementing material. The phosphogypsum-based waste incineration fly ash composite cementing material is prepared from the following raw materials in parts by mass: 70-90 parts of phosphogypsum, 5-20 parts of waste incineration fly ash, 4-13 parts of blast furnace slag powder, 2-9 parts of ash calcium powder, 1.2-2.3 parts of a heavy metal chelating agent, 0.5-2 parts of an alkali activator, 0.2-0.6 part of a water reducing agent and 5-13 parts of water. The phosphogypsum is used as a main base material and cooperates with the waste incineration fly ash, the blast furnace slag powder and the ash calcium powder to prepare the composite cementing material, the construction cost can be remarkably reduced, the performance of the phosphogypsum is improved, meanwhile, the problems that solid waste occupies land, pollutes the environment and wastes resources are solved, and therefore huge economic and environment-friendly benefits are brought.
本发明提供了一种磷石膏基‑垃圾焚烧飞灰的复合胶凝材料及其制备方法和应用，属于磷石膏、垃圾焚烧飞灰综合利用及建筑材料领域。本发明提供了一种磷石膏基‑垃圾焚烧飞灰的复合胶凝材料，由包括以下质量份数的原料制得：磷石膏70～90份、垃圾焚烧飞灰5～20份、高炉矿渣粉4～13份、灰钙粉2～9份、重金属螯合剂1.2～2.3份、碱性激发剂0.5～2份、减水剂0.2～0.6份和水5～13份。本发明以磷石膏为主要基材，协同垃圾焚烧飞灰，高炉矿渣粉，灰钙粉制备复合胶凝材料，可显著降低工程造价，在改善磷石膏性能的同时，解决了固体废弃物占用土地、污染环境和资源浪费问题，从而带来了巨大的经济环保效益。
