A　novel　self-healing　cementitious　composite　SMA-ECC　is　utilized　to　enhance　corrosion　resistance　and　maintain　mechanical　properties　in　chloride　environment.　The　purpose　of　this　study　is　to　investigate　the　impact　of　the　loading　level　on　embedded　steel　rebar　corrosion　and　the　self-healing　performance　of　SMA-ECC.　The　study　examined　the　damage　conditions,　mechanical　properties,　and　rebar　corrosion　resistance　following　a　loading　test.　Chloride　ingress　depth　and　electrochemical　tests　were　adopted　to　evaluate　the　corrosion　resistance　of　the　specimens.　The　findings　reveal　that　SMA-ECC　exhibits　remarkable　self-healing　abilities　in　terms　of　damage　recovery　and　restoration　of　mechanical　properties.　Cracks　smaller　than　50　mu　m　can　achieve　a　100　%　closure　rate　in　SMA-ECC.　It　was　observed　that　specimens　with　less　damage　(50　%,　70　%　damage　conditions)　displayed　improved　chloride　resistance　(SMA-ECC　in　50　%　damage　condition　has　equivalent　corrosion　resistance　in　terms　of　corrosion　current　density　compared　to　intact　NC　control　specimens),　leading　to　higher　corrosion　resistance　for　SMA-ECC　according　to　the　electrochemical　test　results.
