Abstract

The 043-FA concrete bridge in Brazil was built using aggregates susceptible to alkali-silica reactive (ASR), exposed to conditions enabling the development of delayed ettringite formation (DEF) and is still in service. Over the years, many signs of deterioration developed on various structural elements of the bridge, mostly in the foundation blocks and concrete columns. As such, cores were extracted from the structural concrete elements following in-situ inspections. Therefore, this work presents results from the multi-level condition assessment using the damage rating index (DRI) and the stiffness damage test (SDT) to determine the cause and extent of the damage to the concrete due to ASR coupled with DEF. Consequently, elements show a moderate degree of damage (i.e., 0.10–0.15% expansion) except for one foundation block (i.e., B02 at 0.25–0.30% expansion), which displayed an advanced damage level, thus indicating the bridge’s non-conformity to Brazilian safety protocols.
