摘要： The present disclosure is related to the field of steel slag treatment, and in particular to a process for stabilizing steel slag, the process comprising subjecting the steel slag to an autoclave treatment by use of a high temperature and pressure saturated vapor at a pressure of 2.0 MPa or above. The process provides the slag with reliable volume stability and makes it possible to meet desired requirements of various building materials. Additionally, the process is low cost, non-polluting, and of very high industrial value.
