Owing　to　the　unique　molecular　structure　and　high　ion　exchange　capacity,　hydrotalcites　are　believed　to　have　a　potential　to　be　modified　and　tailor-made　as　an　active　corrosion　protective　component　of　reinforced　concrete.　In　this　paper,　two　types　of　modified　hydrotalcites　(MHT-pAB　and　MHT-NO2)　were　tested　both　in　alkaline　solution　and　mortar　for　their　possibilities　as　chloride　scavengers　and　inhibitor　release　agents　for　application　in　concrete.　The　test　in　alkaline　solution　showed　that　ion　exchange　occurred　between　free　chloride　ions　in　solution　and　the　intercalated　inhibitive　anions　in　the　MHTs.　The　results　in　mortar　validated　that　MHTs　could　be　promising　alternatives　for　preventing　chloride-induced　corrosion　when　an　appropriate　dosage　is　adopted　and　applied　in　a　proper　way,　in　particular,　either　incorporation　of　a　certain　amount　(MHT-pAB　to　replace　5%　weight　of　cement)　in　the　bulk　mortar　or　as　a　coating　of　the　reinforcing　steel　(MHT-pAB　or　MHT-NO2　at　20%　weight　of　cement).
