Aerated concrete preparation method based on solid waste resource utilization
The invention discloses an aerated concrete preparation method based on solid waste resource utilization, which comprises the following steps: (1) sequentially adding dry materials silicon tailing mud, iron tailing sand, sludge, waste slurry and titanium dioxide into a dispersion cylinder according to a certain proportion, dispersing at a high speed, sequentially adding cement, lime and desulfurized gypsum, adding aluminum powder paste, quickly stirring uniformly, and pouring; (2) after pouring is completed, performing gas-forming static-stop maintenance and (3) demoulding and carrying out high-temperature steam curing. According to the aerated concrete disclosed by the invention, the silicon tailing mud and the iron tailing sand are used as main siliceous materials, the sludge and the waste slurry are used as secondary siliceous materials, the lime and the cement are used as calcareous materials, the aluminum powder paste is used as a gas-forming agent, and the desulfurized gypsum isused as a regulator of a coagulation process. Compared with the prior art, the autoclaved aerated concrete is prepared by taking industrial by-products such as the silicon tailing mud, the iron tailing sand, desulfurized gypsum and the like as main materials, meanwhile, the comprehensive utilization way of the industrial by-products is expanded, and the circular economy and sustainable developmentconcept of the material is enhanced.
本发明公开了一种基于固废资源化利用的加气混凝土制备方法，包括如下步骤：(1)将干物料硅尾泥、铁尾矿砂、污泥、废浆、钛白粉按一定比例依次加入分散缸后高速分散，接着依次加入水泥、石灰、脱硫石膏，再加入铝粉膏快速搅拌均匀，浇筑；(2)浇筑完毕进行发气静停养护；(3)脱模，高温蒸汽养护。本发明的加气混凝土以硅尾泥和铁尾矿砂为主要硅质材料，污泥和废浆为次要硅质材料、以石灰和水泥为钙质材料、以铝粉膏为发气剂，脱硫石膏作为凝结过程的调节剂；与现有技术相比，以工业副产物硅尾泥、铁尾矿砂、脱硫石膏等作为主要材料制备蒸压加气混凝土的同时，也拓展了工业副产物的综合利用途径，增强了材料的循环经济和可持续发展理念。
