All-solid-waste-based water-permeable brick with adsorption performance and preparation method of all-solid-waste-based water-permeable brick
The invention discloses an all-solid-waste-based water permeable brick with an adsorption property and a preparation method of the all-solid-waste-based water permeable brick. The preparation method is characterized by comprising the following steps: mixing a powdery solid waste raw material consisting of lithium slag, fly ash, silica fume and superfine slag powder, a solid waste aggregate consisting of coal gangue and steel slag, a composite exciting agent solution consisting of a sodium hydroxide solution, sodium-based water glass and a sodium metaaluminate solution, a high-efficiency water reducing agent and water, stirring, pouring, compacting by vibration and curing. According to the water permeable brick prepared by the invention, the industrial solid waste is used as a main raw material, and the bonding strength and the water permeable rate among aggregates of the water permeable brick are improved by matching a composite exciting agent and gradient curing conditions, and a zeolite-like component with adsorption capacity on pollutants such as heavy metal ions and the like can be generated; therefore, the resource utilization level of industrial solid waste is improved, and good comprehensive benefits are also achieved for urban inland inundation and rain sewage purification.
本发明公开了一种具备吸附性能的全固废基透水砖及其制备方法，其特征是将锂渣‑粉煤灰‑硅灰‑矿渣微粉组成的粉状固废原料、煤矸石‑钢渣组成的固废骨料、氢氧化钠溶液‑钠基水玻璃‑偏铝酸钠溶液组成的复合激发剂溶液、高效减水剂、水经混合‑搅拌‑浇注‑振实‑养护工艺形成。本发明所制备的透水砖以工业固废作为主要原料，通过匹配复合激发剂和梯级养护条件，不仅提高了透水砖骨料间的粘结强度和透水率，而且能够生成具有重金属离子等污染物吸附能力的类沸石组分，从而提高了工业固废的资源化利用水平，对城市内涝及雨污净化同样具有良好的综合效益。
