Two　kinds　of　layered　double　hydroxides　(LDHs),　MgAl-NO2　(N-LDH)　and　MgAl-CO3　(C-LDH),　were　incorporated　to　study　the　durability　of　mortar　and　concrete.　The　LDH　contents　of　mortar　were　1%,　2%,　and　4%　by　mass　and　the　LDH　contents　of　concrete　were　0.5%,　1%,　2%,　4%,　respectively.　The　effect　of　LDHs　on　sulfate　resistance　of　mortar　was　studied　through　dry-wetting　cycle　test,　compressive　strength　test,　and　flexural　strength　test.　In　addition,　the　effects　of　LDHs　on　pore　structure,　chloride　resistance,　carbonation　resistance,　shrinkage,　and　creep　of　concrete　were　investigated　by　SEM,　mercury　injection　test,　XRD,　chloride　ion　diffusion　coefficient　test,　chloride　salt　corrosion　depth　test,　carbonation　depth　test,　shrinkage　test,　and　creep　test.　The　results　showed　that　LDHs　can　improve　the　ability　of　resisting　ion　corrosion,　carbonization,　shrinkage,　and　creep,　reduce　the　pore　content,　and　optimize　the　pore　structure　of　mortar　and　concrete　to　some　extent.　Moreover,　4%　LDHs　had　a　better　effect　on　improving　the　durability　of　mortar　and　concrete　compared　to　0.5%,　1%,　and　2%　LDHs,　and　the　effect　of　C-LDH　was　better　than　N-LDH.
