Open publisher page 1 citations

Abstract

Based on an analysis to the basic theory of rebar corrosion in chloride containing concrete, this paper introduces the preliminary results of the experiment on the rebar accelerated corrosion in concrete in the man made climate chamber. Results showed that temperature and relative humidity had great influences on the rebar corrosion rate in chloride containing concrete. The speed of rebar corrosion increases with temperature and relative humidity. The experiment also showed that the thickness of concrete cover and the diameter of rebar also had apparent effect on the corrosion rate.
