Magnesium alloy anode as a smart corrosivity detector and intelligent sacrificial anode protector for reinforced concrete

Corrosivity of simulated concrete pore solution (SCPS) contaminated by chloride was automatically detected and corrosion of steel in SCPS was intelligently prevented by magnesium (Mg) alloy. Results indicated that Mg could act as effective sacrificial anode to cathodically protect steel from corrosion attack once the SCPS was polluted by chlorides. Al alloying could enhance the sensitivity of Mg anode to chloride contamination and further...
