The material after stabilization was Free CaO (f-CaO) Content rapid quantitative test of mixing Stainless Steel Oxidizing Slag cement mortar. Stainless Steel Oxidizing Slag substituted for fine aggregates with various percentages (0%, 25%, 50%, 75%, 100%, by weight), to investigate the effects of different stabilization on workability. The irrigation system complete test body were Autoclave expansion test, High-temperature rapid catalysis test, Microwave Catalysis test, Compressive strength test, Ultrasonic pulse velocity test. The results show that the material produced by the test body High-temperature oxalic acid solution stabilization in Autoclave expansion test, High-temperature rapid catalysis test and Microwave Catalysis test have a smaller volume expansion, Compressive strength test and Ultrasonic pulse velocity test is not stable with time.
