Old reinforced concrete structure with damaged and rusty metallic reinforcement bars.
the Program 2023

Preliminary Program

Special sessions are organised during the workshop. Authors are   invited to kindly select the session at which they will present their papers. Each session will include both research and engineering applications focussing on what is needed for the evaluation of corroded structures.

CACRCS DAYS 2023 includes a Round table to promote discussions.

The workshop offers didactic material for engineers, practitioners, scientists, concrete technologists, researchers, and academics to further knowledge about corrosion of reinforced concrete structures.
