| Outline of Final Research Achievements |
In this study, it was found that long term leaching behavior of heavy metals which may be contained in concrete due to effective utilization of industrial wastes is different in environmental conditions where concrete structures are placed, however modeling of heavy metal leaching considering its adsorption properties on concrete has not been finalized. Regarding environmental impacts, it was clarified that the impacts should be calculated considering heavy metal leaching amounts together with gas emissions, however the setting conditions for the calculation of leaching amounts could not be specified.
