Production process and device for mineralizing and strengthening construction waste and mineralizing and curing concrete products by using cement kiln tail gas
The invention provides a production process and device for mineralizing and strengthening construction waste and mineralizing and curing concrete products by using cement kiln tail gas. The average water absorption rate of coarse and fine aggregates of the mineralized and reinforced construction waste can be reduced by 15% or above, and the activity index of the construction waste micro powder is improved by 15% or above; the compressive strength of the mineralized curing concrete product is improved by more than 40% compared with that of a standard curing concrete product at the same age. According to the invention, the tail gas of the cement kiln of the cement enterprise is fully utilized, the carbon dioxide of the concrete product in the whole process from raw materials to product production is sealed and utilized, the utilization rate of the construction waste is improved, the resources are saved, the environment is protected, and a feasible path is provided for realizing the carbon neutralization target.
本发明提供一种利用水泥窑尾气矿化强化建筑垃圾及矿化养护混凝土制品的生产工艺及装置。本发明矿化强化建筑垃圾的粗细骨料平均吸水率可降低15％以上，建筑垃圾微粉活性指数提高15％以上；矿化养护混凝土制品的抗压强度比同龄期标准养护混凝土制品抗压强度提升40％以上。本发明充分利用了水泥企业水泥窑尾气，实现了混凝土制品从原材料到制品生产全过程的二氧化碳封存利用，提高了建筑垃圾的利用率，既节约了资源，保护了环境，还为实现碳中和目标提供了一条切实可行的路径。
