Method for preparing recycled concrete for roads from industrial waste residues
The invention discloses a method for preparing recycled concrete for roads from industrial waste residues, the method comprises the following steps: S1, putting steel slag collected after steelmaking into a cleaning pool, washing the steel slag, and removing dust attached to the steel slag, S2, filtering out the cleaned steel slag through a filtering device, putting the steel slag into a drying box, and performing quick drying, S3, putting the dried steel slag into a grinding machine for grinding to obtain steel slag powder, and S4, after the steel slag is dried, putting the steel slag into an electric furnace for heating and smelting at the moment so that the steel slag is in a high-temperature state until iron contained in the steel slag is molten. According to the method, iron contained in the steel slag can be completely removed in a heating mode so that it can be guaranteed that no iron is contained in concrete during later concrete manufacturing, the stability of the concrete can be guaranteed, and the equipment has good practicability.
本发明公开了一种利用工业废渣制备的道路用再生混凝土的方法，包括以下步骤：S1：将炼钢后收集到的钢渣投放至清洗池内，对钢渣进行淘洗，去除钢渣上所附着的灰尘，S2：将清洗后的钢渣经过过滤设置滤出，之后将钢渣投放至烘干箱内，进行快速烘干，S3：将烘干后的钢渣投放至研磨机内，进行研磨，得到钢渣粉末，S4：在将钢渣烘干之后，此时可将钢渣投放至电炉内进行加热冶炼，使得钢渣处于高温状态，直至将钢渣内所含有的铁进行融化。本发明能够实现对钢渣采用加热的方式将钢渣内所含有的铁全部去除，以此能够保证后期在制作混凝土时，保证混凝土内不含有铁，能够保证混凝土的稳定性，所以具有良好的实用性。
