Abstract:	摘要： •Autoclaving causes cracking loss of furnace slag aggregate particles.•The expansion of mortar bar at 215.7°C is about 2.4 times than that at 170.0°C.•Autoclave pretreatment is an effective method to inhibit the expansion of slag.•The time for stabilizing furnace slag is related to the property of the slag itself.•The stability of slag can be checked by the autoclave expansion of slag mortar bar. Furnace slag was stabilized in an autoclave environment and then transformed into a mortar bar for the autoclave test. The expansion capacity of the slag mortar bar was observed to evaluate the feasibility of stabilizing slag expansion through the autoclave method. Results showed that the pretreatment of furnace slag by autoclave method is effective in stabilizing slag. The required time for stabilizing furnace slag is related to the property of the slag itself. Slag is completely stabilized when the expansion capacity of the slag mortar bar does not exceed 0.052% after three hours of autoclave at 215.7°C. 出版者： Elsevier Ltd 出版日期： 2014-10-15 出處： Construction & building materials, 2014-10, Vol.68, p.552-557 版權： 2014 Elsevier Ltd 版權： COPYRIGHT 2014 Elsevier B.V. 識別號： ISSN: 0950-0618 識別號： DOI: 10.1016/j.conbuildmat.2014.06.082
