Reclamation Information Sharing Environment (RISE)

Reclamation has numerous concrete structures suffering from deterioration due to alkali-silica reaction (ASR) that need repair. It is widely known what characteristics a repair material should have to mitigate ASR within the repair material itself, but there is a need for better understanding of how the repair material may affect existing concrete with ASR and the bond between the two. This report summarizes the results of bond testing performed on control and ASR reactive slabs overlayed with four different concrete repair materials.
