Studies　of　chloride-induced　corrosion　in　reinforced　concrete　structures　are　performed　based　on　the　reliable　predictions　of　chloride　and　moisture　distributions　in　concrete.　This　paper　adopted　the　Laplace　Transformation　and　the　inverse　Laplace　Transformation　to　obtain　the　analytical　solutions　of　the　moisture-chloride　two-way　coupled　transport　processes.　Additionally,　the　model　has　involved　with　realistic　material　parameters　to　predict　the　internal　distributions　of　relative　humidity　and　free　chloride　ions　in　concrete　samples.　To　illustrate　the　accuracy　of　the　present　model,　the　calculations　were　compared　with　the　available　experimental　results,　and　good　agreements　were　obtained.　It　indicates　that　the　present　analytical　model　can　successfully　characterize　the　two-way　coupling　effects　between　chloride　transport　and　moisture　diffusion　in　concrete;　and　the　model　can　provide　the　distribution　profiles　of　both　chloride　and　relative　humidity　in　concrete,　which　are　useful　for　predicting　the　service　life　of　reinforced　concrete　structures.
