High specific surface area MMT/NO intercalated modified MgAl-LDH core-shell composites: effective inhibition for steel in Cl contaminated saturated Ca(OH) solution.

This study developed nitrate-intercalated layered double hydroxides (NO-LDHs) and their core-shell composites (NO-LDHs@MMT) through an co-precipitation method with montmorillonite (MMT). The corrosion inhibition performance for Q235 steel in simulated concrete pore solutions (saturated Ca(OH) + 3.5 wt% NaCl) was systematically investigated.
