- Abstract
- Chloride ions ingress continuously in reinforced concrete through pores of it by Cl-. Recently, new materials removing harmful anions have been developed. Layered double hydroxides(LDH) has an excellent ability to remove harmful anions because various anions can be adsorbed in the interlayer space between divalent and trivalent cations. In this study, Ca/Al-NO3 and Mg/Al-NO3 LDH were prepared by using a co-precipitation method. Experiments for binding chloride ions of LDH were conducted by using potentiometric method.
