Preparation method of solid-waste-based high-strength low-water-absorption unfired artificial aggregate
The invention discloses a preparation method of solid-waste-based high-strength low-water-absorption type baking-free artificial aggregate. The method comprises the following steps: mixing solid wastes (quartz tailings, fly ash, desulfurized gypsum and the like) which are difficult to treat and have low gelation activity according to a certain mixing ratio, and carrying out static pressure shaping process and low-carbon curing process; the preparation method can be used for rapidly preparing the angular baking-free artificial aggregate with low bulk density, low water absorption rate and high strength in a short time, realizes harmless treatment of solid wastes, improves the site rotation efficiency of factories, and increases the application scenarios of the aggregate. According to the method, the environmental influence, the production energy consumption and the period are reduced to the greatest extent while the efficient resource utilization of the multi-source solid wastes is realized, so that the structural layout of the sandstone industry is optimized, and the green transformation and sustainable development of the industry are realized.
本发明公开了固废基高强度、低吸水率型免烧人工骨料的制备方法。所述方法将难以处理处置及具有低胶凝活性的固体废弃物(石英尾矿、粉煤灰和脱硫石膏等)按照一定的配合比混合后，采用静压整形工艺和低碳养护工艺，在较短的时间内快速制备具有低堆积密度、低吸水率、高强度和棱角形的免烧人工骨料，实现固体废弃物的无害化处理处置并提升工厂场地轮转效率，增加其应用场景。本发明在实现多源固体废弃物资源化高效利用的同时，最大程度地降低环境影响、生产能耗和周期，从而优化砂石产业结构布局，实现行业绿色转型及可持续发展。
