Description

Bond degradation has become a common, and sometimes critical problem for aging concrete bridges. Corrosion due to sea water, water pollution, acid rain as well as high salt content in concrete and its composition are threatening the structure integrity. Among the issues related to corrosion prevention and inspection, bond strength is of great concern [1,2]. The bond strength and fiber pull-out have between fiber and surrounding composite materials have been studied by Cairns and Jones[3], Kim et al. [4] and Naaman et al. [5]. Both bond split and slip are of interests for cement-based matrices and steel reinforcing bars (so called rebar). Current study is part of an investigation aiming to simplify the inspection of corrosion and to improve the analysis of bond strength for steel reinforced concrete structure.
