Bond strength of RC elements with consideration of corrosion: An experimental survey

Abstract

The researches on the bond behavior of corroded reinforcements are finalized to the assessment of the structural serviceability loss, providing appropriate tools for the evaluation of the structural integrity, i.e. relation between the corrosion rate and the cracks width detected during visual inspection on existing structures. Unfortunately, several contradictions can be found in the literature and a comprehensive interpretation of the influence of both the concrete cover depths and the reinforcement typology on the corrosion process is still missing. The present work describes the research activities planned in the convention "Effect of corrosion on the steel-to-concrete interaction" and finalized to understand the bond-slip decay in presence of corrosion.
