Cement waste incineration fly ash cementation building solid waste negative carbon baking-free building block
The invention relates to a cement waste incineration fly ash cemented building solid waste negative carbon baking-free building block which is prepared from building solid waste, cement and waste incineration fly ash, the building solid waste is a coarse-grained material formed by mechanically crushing and screening waste concrete blocks, decoration garbage and the like, the mass ratio of the building solid waste to the negative carbon baking-free building block is 80-85%, the mass ratio of the waste incineration fly ash to the cement is 15-20%, and the mass ratio of the waste incineration fly ash to the cement is 1.0-1.5; the negative carbon baking-free building block is prepared by the following steps: performing harmless treatment on the waste incineration fly ash by using a chelating agent with the concentration of 50-100g/L, controlling the mass ratio of the fly ash to the chelating agent to be (16: 10)-(16: 8), performing dry mixing on the building solid waste, the waste incineration fly ash and the cement, uniformly mixing with water, and finally performing forging and pressing, pouring and molding, pre-curing and carbon curing. The negative carbon baking-free building block disclosed by the invention is excellent in performance, realizes effective treatment of building solid waste and waste incineration fly ash, and is beneficial to construction of resource economy and environment-friendly society.
一种水泥垃圾焚烧飞灰胶结建筑固废负碳免烧砌块，由建筑固废料、水泥和垃圾焚烧飞灰制成；建筑固废料是指废旧混凝土块、装修垃圾等经机械破碎、筛分形成的粗粒材料，其在负碳免烧砌块中的质量占比为80‑85%，垃圾焚烧飞灰和水泥占15‑20%，两者质量之比为1.0‑1.5；所述负碳免烧砌块首先用浓度50‑100g/L螯合剂对垃圾焚烧飞灰进行无害化处置，飞灰与螯合剂质量比介于16:10‑16:8，再将建筑固废料、垃圾焚烧飞灰、水泥干混后与水拌合均匀，最后锻压、浇筑成型，先预养护，再碳养护。本发明负碳免烧砌块性能优良，实现建筑固废和垃圾焚烧飞灰有效处置，利于资源经济和环境友好型社会的建设。
