Preparation method of solidified waste ash type novel mineral powder
The invention relates to a preparation method of solidified waste ash type novel mineral powder, which mainly comprises the following steps: crushing solidified waste ash lumps formed by solidifying waste fly ash discharged from a waste incineration plant by using a solidifying agent and industrial waste residue nickel slag discharged from a nickel product production plant according to a certain proportion to prepare a mixture; reacting in a drying kiln to 100-200 DEG C to obtain an active glass body; and grinding the active glass body into a novel mineral powder material by taking C12A7 and C2S as main mineral composition materials. The other industrial waste residues such as solidified waste ash blocks which are piled up like mountains, pollute the environment and are difficult to treatcan be turned into wealth, and a solidified waste ash type novel mineral powder product which can completely replace slag powder which is short in resource and continuously rises in price is obtainedthrough treatment. Various properties of the produced novel mineral powder product can reach or exceed the quality indexes of slag powder, the mineral powder product is a high-quality cement and concrete admixture, the maximum doping amount of the mineral powder product in cement and concrete can reach 60%, and the mineral powder product is a good method for turning waste into wealth and conducting harmless treatment.
本发明的固化垃圾灰式新型矿粉的制备方法，主要是将垃圾焚烧厂排出的垃圾飞灰用固化剂固化成的固化垃圾灰块状体，和生产镍产品厂排出的工业废渣镍渣，通过破碎按一定比例制成混合料，经干燥窑至100‑200度反应成活性玻璃体以及C12A7和C2S为主要矿物组成材料粉磨成的新型矿粉材料等步骤。能将堆积如山既污染环境又难以处理的固化垃圾灰块状体等其它工业废渣变废为宝，处理成完全可以替代资源短缺且价格不断上涨的矿渣粉使用的固化垃圾灰式新型矿粉产品。生产的新型矿粉产品的各种性能都能达到或超过矿渣粉的质量指标，是一种优质水泥和混凝土掺合料，在水泥和混凝土中最大掺入量可达60％，是一种变废为宝无害化处理的好方法。
