This work expects to consume slag waste on environment, and provide a low-cost concrete, waste-to-resource technologies and the enhancement of value addition in the mixture. In this experiment, stainless steel oxidizing slag expose outdoor of the natural environment in different time courses was Free CaO (f-CaO) Content rapid quantitative test of mixing Stainless Steel Oxide Slag cement mortar. Stainless Steel Oxidizing Slag substituted for fine aggregates with various ratios (e.g.0%, 25%, 50%, 75%, 100%),to investigate the effects of different stabilization on workability, The cement mortar were Autoclave expansion test, High-temperature rapid catalysis test, Microwave Catalysis test, Compressive strength test, Ultrasonic pulse velocity test, SEM, XRD. The results show that Stabilization have an impact on expansion behavior, but compressive strength, fresh engineering, ultrasonic pulse velocity has little effect, On the specimens suggest that Ca(OH)2 can instantly squeeze and rupture during high-temperature rapid catalysis.
