Alkali-activated furnace bottom ash baking-free brick and preparation method thereof
The invention relates to a preparation method of an alkali-activated furnace bottom ash baking-free brick, which comprises the following steps: pre-soaking coarse aggregate and fine aggregate, and airing to a saturated surface dry state; preparing an exciting agent, and sealing and aging the prepared exciting agent for more than 4 hours; the preparation method comprises the following steps: weighing the exciting agent, the coarse aggregate, the fine aggregate, the furnace bottom ash, the slag and the water, uniformly stirring in a stirrer, pouring the uniformly stirred material into a mold, compacting by inserting and tamping, and carrying out steam curing on the prepared standard brick at 60-80 DEG C for 6-10 hours. The baking-free brick prepared in the whole scheme process is subjected to steam curing for 6-10 h at the temperature of 60-80 DEG C and then subjected to natural curing, the sintering process is avoided, energy consumption can be reduced, and the production cost can also be properly reduced. And meanwhile, most of the raw materials used in the invention are solid wastes, so that the use of natural aggregates and non-renewable resources is reduced, the problem that a large amount of furnace bottom ash is stacked to occupy land resources can be solved, and the environment can be properly protected.
本发明涉及一种碱激发炉底灰免烧砖的制备方法，该方法包括将粗骨料和细骨料预先浸泡，并晾晒至饱和面干状态；配制激发剂，将配置好的激发剂密封陈化4小时以上；称取激发剂，粗骨料、细骨料、炉底灰、矿渣和水于搅拌机中搅拌均匀，将搅拌均匀的材料浇筑在模具中，插捣密实，制备好的标准砖在60℃~80℃蒸汽养护6~10h。本发明在整个方案过程中所制备的免烧砖在60℃‑80℃蒸汽养护6‑10h后再自然养护，无烧结这一过程，不仅可以减少能耗的产生，也可以适当降低生产成本。同时本发明使用的原材料大都是固体废弃物，减少了天然骨料及不可再生资源的使用，不仅可以解决炉底灰大量堆放占用土地资源这一问题，也可以适当保护环境。
