A Fundamental Study on the Steel Slag Aggregate for Concrete
Compared with the blast furnace slag, steel slag has the expansibility due to the reaction with water and free CaO. Therefore it is specified in Standard Specification for Concrete in Korea that steel slag aggregate must not be used in concrete. So it is unusual to use steel slag aggregate in concrete. In this study steel slag aggregate processed by several aging process was comparatively satisfied with fundamental properties as concrete aggregate, which are specific gravity, absorption, unit weight, percentage of solids and abrasion value etc. Chemical analysis is also observed to understand the effect of aging process in steel slag aggregate. When the strength is measured, it is found that the concrete replacing crushed stone with unstable steel slag aggregate had a little problem.
