A Study on Compressive Strength and Microstructure Properity of Reactive Powder Concrete Containing Copper Slag as Aggregate
Kim, Young Su; Lee, Yong Mu;
Thesedays, ultra high strength concrete that exceeds compressive strength of 100MPa is used widely in modern structure. Reactive powder concrete is an ultra high strength cement-based material. In this study, copper slag has been replaced with quartz sand at 10, 20, 30, 40and 50 %. Three different curing methods(water, steam and autoclave curing) were applied to the specimens. After mixing, tests of mini slump flow, unit volume weight and amount of air were conducted on fresh reactive powder concrete. Compressive strength was determined after 28days on the hardened reactive powder concrete specimens. Test results of compressive strength of reactive powder concrete containing copper slag was over 200MPa after autoclave curing.
