The　service　life　of　reinforced　concrete　structures　is　significantly　affected　by　the　chloride-induced　corrosion　of　reinforcing　steel.　This　paper　presents　a　comprehensive　study　on　the　influence　of　the　corrosion　environment　and　other　parameters　on　the　corrosion　rate　of　reinforcing　steel　in　concrete.　Comparative　tests　were　carried　out　on　concrete　block　and　beam　specimens　subjected　to　accelerated　corrosion　in　indoor　and　outdoor　environments　for　a　period　of　1.5　years.　The　experimental　variables　considered　included　the　chloride　content,　depth　of　concrete　cover,　type　of　reinforcing　steel　and　water-to-cement　(w/c)　ratio.　The　test　results　indicated　that　the　corrosion　rate　of　the　reinforcing　steel　increases　with　the　increase　in　the　w/c　ratio,　chloride　content,　temperature　and　relative　humidity,　while　it　is　reduced　when　the　thickness　of　the　concrete　cover　increases.　Furthermore,　an　empirical　model　for　predicting　the　corrosion　rate　of　reinforcing　steel　in　concrete　is　proposed　using　the　experimental　data,　which　offers　a　good　prediction　of　the　corrosion　rate.
