000002197 520__ $$2eng$$aChloride induced corrosion was recognized as one of the major cause of degradation of reinforced concrete structures, layered double hydroxides (LDHs) materials could be used in cement and concrete for their ions capturing capacity and to enhance durability of concrete. Properties and chloride binding capacity of different types of LDHs were compared, micro-mechanism of chloride binding of LDHs were analyzed, chloride binding of cement paste incorporating LDHs, workability and compressive strength and chloride diffusion of concrete incorporating LDHs were investigated. The experimental results show that: (1) Mg-Al-NO3 LDHs presents higher chloride ion binding capacity at initial time compared to LDOs calcinated at 500°C. (2) Cement paste incorporating LDHs presents higher chloride binding capacity. (3) All types of LDHs performed beneficial effect on the chloride penetration resistance especially with addition of 1% Mg-Al-NO3 LDOs.
