제강슬래그를 이용한 친환경콘크리트의 개발 = Development of the Environmentally Friendly Concrete Using Steel Slag

다국어 초록 (Multilingual Abstract)

In order to develop of the environmentally friendly concrete(EFC) using steel slag of Gwangyang steelworks as coarse aggregate, physical properties of steel slag aggregate were estimated. The leached harmful substances from steel slag and EFC were compared with those of Korean Standard(KS). Also porosity, coefficient of permeability, and strength of FEC were measured and compared with those of 2 kinds of codes and porous concrete using crushed stone.
As the results, the steel slag corresponded with concrete aggregate of Korea Industrial Standard. Harmful substances of steel slag and EFC were safe less than those of KS. Although coefficient of permeability of EFC was contented with 2 kinds of codes, porosity didn`t attain certification criteria of vegetation pavement materials of Korea Environmental Industry & Technology Institute. Even though the compressive strength of EFC reached 2 kinds of codes, the results of tensile and flexural strength were confirmed that they were more vulnerable than the porous concrete using the crushed stone.
