CO2 carbonization treatment steel slag-based aerated block and preparation method thereof
The invention relates to a CO2 carbonization treatment steel slag-based aerated block which comprises the following components: a cementing material, an air entraining agent, a foam stabilizer and water, the preparation method comprises the following steps: preparing a cementing material mixture, preparing a suspension solution, preparing a slurry material, pouring and molding, demolding after curing, and carbonizing and curing. The preparation process adopts a method for producing the aerated block without a high-pressure steam curing process, and a building material product is prepared through a tail gas carbonization process, so that good social and economic benefits are achieved; the preparation material takes the steel slag as a main raw material, so that the maximum resource utilization of the industrial solid waste steel slag is realized, and the problem of secondary pollution to the environment caused by cultivated land occupied by steel slag accumulation is solved; the steel slag contains more free CaO and MgO, the free CaO and MgO can be effectively aged and digested through a carbonization process, and the problem of volume stability of the steel slag is avoided; the carbonized steel slag aerated block has the characteristics of light weight, high strength and porosity, and has the advantages of good heat preservation, heat insulation and sound insulation.
本发明涉及一种CO2碳化处理钢渣基加气块，包括以下组分：胶凝材料、引气剂、稳泡剂、水；制备方法，包括以下步骤：制胶凝材料混合物、制悬浮溶液、制浆料、浇筑成型、养护后脱模、碳化养护。制备工艺采用免高压蒸养工艺生产加气块的方法，通过尾气碳化工艺制成建材产品，具有良好的社会和经济效益；制备材料以钢渣为主要原料，实现了最大化工业固废钢渣资源化利用，又解决了钢渣堆积占用了耕地对环境造成二次污染的问题；钢渣中含有较多的游离CaO、MgO，通过碳化工艺方式可有效被陈化消解，避免钢渣出现的体积安定性问题；碳化处理的钢渣加气块具有轻质、高强、多孔的特性，具有良好的保温隔热、隔音的优点。
