Electrolytic manganese residue low-carbon roadbed material and preparation method thereof
The invention discloses a preparation method of an electrolytic manganese residue low-carbon roadbed material, which comprises the following steps: crushing original electrolytic manganese residues to obtain pretreated electrolytic manganese residues; a deamination manganese fixing agent and the pretreated electrolytic manganese residues are subjected to first mixing, and a first mixture is obtained; the first mixture is subjected to tedding treatment, and a second mixture is obtained; mineral powder and aggregate are added into the second mixture for second mixing, a third mixture is obtained, the mineral powder accounts for 4%-10% of the dry material of the third mixture, and the aggregate accounts for 15%-35% of the dry material of the third mixture; and paving, rolling and maintaining the third mixture to obtain the low-carbon roadbed material. According to the method, the electrolytic manganese residues are combined with the mineral powder and the aggregate after being subjected to deamination and manganese fixation treatment, so that the engineering performance such as the strength of a solidified body is improved, meanwhile, resource utilization is achieved, and the purposes of turning waste into wealth and treating waste with waste are achieved.
本发明公开了一种电解锰渣低碳型路基材料的制备方法，包括：将原样电解锰渣破碎处理，获得预处理电解锰渣；将脱氨固锰剂与所述预处理电解锰渣进行第一拌合，获得第一混合料；将所述第一混合料进行翻晒处理，获得第二混合料；将矿粉和集料加入所述第二混合料中进行第二拌合，获得第三混合料，其中，所述矿粉占所述第三混合料干料的4％～10％，所述集料占所述第三混合料的干料的15％～35％；将所述第三混合料进行摊铺碾压和养护，获得低碳型路基材料。本发明将电解锰渣脱氨固锰处理后与矿粉、集料结合，从而增加固化体强度等工程性能，同时实现资源化利用，实现了变废为宝，以废治废的目的。
