Method for preparing modified geopolymer porous brick from waste incineration fly ash
The invention provides a method for preparing a modified geopolymer porous brick from waste incineration fly ash, which comprises the following steps: carrying out dioxin cracking on fly ash, and washing to obtain a washing product; performing first mixing on the washing product, fly ash, kaolin and Portland cement to obtain a first mixture; performing second mixing on the first mixture and an alkaline activator to obtain a second mixture; performing third mixing on the second mixture and a foaming agent to obtain slurry; and molding the slurry, and curing to obtain the geopolymer porous brick. According to the method provided by the invention, harmlessness and recycling of the waste incineration fly ash can be realized, and the perforated brick is excellent in performance, has relatively high compression resistance and breaking strength, and can be used as a non-structural light-weight fire-resistant thermal insulation material.
本发明提供了一种垃圾焚烧飞灰制备改性地聚物多孔砖的方法，包括：将飞灰进行二噁英裂解后进行水洗，得到水洗产物；将所述水洗产物、粉煤灰、高岭土和硅酸盐水泥进行第一混合，得到第一混合物；将所述第一混合物和碱性激发剂进行第二混合，得到第二混合物；将所述第二混合物和发泡剂进行第三混合，得到浆体；将所述浆体进行成型后养护，得到地聚物多孔砖。本发明提供的方法可实现垃圾焚烧飞灰无害化及资源化，该多孔砖性能优良，具有较高的抗压及抗折强度，可作为非结构性轻质耐火保温材料使用。
