Chloride binding by calcined layered double hydroxides and alumina-rich cementitious materials in mortar mixed with seawater and sea sand

Seawater and sea sand can alleviate the shortage of resources and reduce the transportation distance of raw materials at the construction of offshore islands, whereas the high content of chloride ions in concrete mixed with seawater and sea sand induces reinforcement corrosion, which is the biggest obstacle to its wide application. This study aims to explore the way to reduce the free chloride ions content and improve the chloride binding...
