In　order　to　investigate　the　corrosion　performance　of　reinforced　concrete　in　the　marine　environment,　the　seawater　hot　rain　testing　(SHRT)　equipment　was　used　to　imitate　the　marine　environment　and　accelerate　corrosion　rate　by　circularly　spraying　seawater　to　the　samples　under　high　temperatures　which　can　attain　70°C.　The　test　results　show　that　SHRT　can　accelerate　the　chloride　ion　permeability　which　can　quickly　investigate　the　corrosion　performance　of　reinforced　concrete.　Different　types　of　material　admixtures　have　different　influences　on　the　corrosion　performance　of　reinforcement　concrete,　and　rust　inhibitor　and　cementitious　capillary　crystalline　material　can　improve　the　anti-rust　resistance　of　reinforced　concrete　effectively.　©　(2013)　Trans　Tech　Publications,　Switzerland.
