The invention provides a house refuse burning fly ash curing stabilization gel material. The material is prepared from 55-85% by mass of mineral waste residues, 5-25% by mass of a clinker, 0-10% by mass of sodium chloride, 0-10% by mass of gypsum and 2-8% by mass of an alkaline exciting agent. The house refuse burning fly ash curing stabilization gel material is prepared from cheap and easily available raw materials through simple and easy processes, is insensitive to ingredients of house refuse burning fly ash, can be used for curing stabilization treatment on most of fly ash, has obvious curing effects, guarantees heavy metal long-term stability, effectively prevents fly ash-caused secondary pollution on the environment, and solves existing pressing issues of the waste incineration plant and fly ash-caused damage to environmental protection and human body health. 本发明提供了种生活垃圾焚烧飞灰固化稳定化胶凝材料，包括按质量百分比计的如下组分：矿渣55～85%，熟料5～25%，氯化钠0～10%，石膏0～10%，碱性激发剂2～8%。该生活垃圾焚烧飞灰固化稳定化胶凝材料的原材料廉价、易得，且修复方法简单、易行，对垃圾焚烧飞灰本身成分不敏感，可用于绝大部分飞
