Carbonized steel slag building material product prepared from cement kiln tail flue gas and method thereof
The invention relates to the field of comprehensive utilization of resources, in particular to a carbonized steel slag building material product prepared from cement kiln tail flue gas and a preparation method of the carbonized steel slag building material product. The method comprises the following steps: mixing steel slag powder, cement, water, sand and an additive in proportion, hardening under a standard curing condition, and then carbonizing in a cement kiln tail gas kiln to obtain the carbonized steel slag building material product. According to the method disclosed by the invention, the steel slag product is carbonized by utilizing the cement kiln tail flue gas, and the steel slag is converted into the building material product, so that the maintenance period of the steel slag building material product is effectively shortened, the carbon emission of cement enterprises is remarkably reduced, CO2 in the flue gas is turned into wealth, and the problem that the steel slag is difficult to utilize is solved; meanwhile, the temperature of the tail flue gas of the cement kiln is fully utilized in the whole technological process, additional energy consumption is not needed, and the requirement for carbonization reaction equipment and the overall cost are reduced. The steel slag building material product prepared by the method is good in stability and excellent in comprehensive performance, and has a wide application prospect.
本发明涉及资源综合利用领域，尤其涉及一种利用水泥窑尾烟气制备的碳化钢渣建材制品及其方法。该方法包括：将钢渣粉、水泥、水、砂和外加剂按比例混合，在标准养护条件下进行硬化，然后在水泥窑尾废气窑内进行碳化处理，得到碳化钢渣建材制品。本发明方法利用水泥窑尾烟气对钢渣制品进行碳化处理，将钢渣转化为建筑材料制品，有效缩短了钢渣建材制品的养护周期，显著降低了水泥企业的碳排放将烟气中的CO2变废为宝，解决了钢渣难以利用的问题，同时整个工艺流程充分利用了水泥窑尾烟气的温度，无需额外能耗，降低了碳化反应设备要求和整体成本。本发明方法制备的钢渣建材制品安定性良好且综合性能优异，拥有广泛的应用前景。
