Abstract

Abstract:

It is well known that the stacking of electrolytic manganese slag threatens people's health and the ecological environment，so the harmless treatment of electrolytic manganese residue becomes an urgent problem to be solved.The soluble Mn and Cr in electrolytic manganese slag were solidified in the grain by sintering at 1 100 ℃，and the ompound salt containing ammonia were thermal decomposed at same time.The electrolytic manganese slag after sintering at high temperature had been porcelain and had high compressive strength，which could replace the aggregate in concrete after breaking and classifying.The results showed that the coarse aggregate and fine aggregate of electrolytic manganese slag ceramic could meet the standard of “recycled coarse aggregate for cement”.XRD and EDS analysis showed that electrolytic manganese slag after sintering contained a certain amount of CaSO₄，the presence of CaSO₄ promoted the synthesis of calcium vanadite，the hydration product of cement，so that the ceramic aggregate and cement were more closely combined，and the ceramic aggregate did not fail in the form of pulling out when the concrete test block was broken，and the mechanical strength of the concrete test block was increased.The 14 d flexural strength of the concrete sample prepared with ceramic coarse aggregate and natural sand fine aggregate was 7.54 MPa，which was better than that of the sample with both coarse aggregate and fine aggregate as natural sand and stone（5.36 MPa）.The coarse ceramic aggregate accounted for 48.55% in concrete，and the amount was large.This study was of great significance for the resource utilization of electrolytic manganese slag.

Key words: electrolytic manganese slag, ceramic aggregate, CaSO₄, solid waste, resource utilization, concrete
