This memory presents the initial results on the inhibition of rebar corrosion in a carbonated concrete containing chlorides by using a mix of two substances, one efficient towards the attack of chlorides, the other towards the carbonation effects. This research aims at confirming in concrete the positive results previously obtained in a synthetic solution simulating the electrolyte in a chloride-polluted carbonated concrete. Impedance measurements has been applied to study rebar corrosion inhibition in concrete and an equivalent circuit has been proposed to interpret the impedance data. 6-month tests confirmed that this mix of two inhibitors can efficiently retard rebar corrosion in carbonated and chloride polluted concrete.

Abstract
This memory presents the initial results on the inhibition of rebar corrosion in a carbonated concrete containing chlorides by using a mix of two substances, one efficient towards the attack of chlorides, the other towards the carbonation effects. This research aims at confirming in concrete the positive results previously obtained in a synthetic solution simulating the electrolyte in a chloride-polluted carbonated concrete. Impedance measurements has been applied to study rebar corrosion inhibition in concrete and an equivalent circuit has been proposed to interpret the impedance data. 6-month tests confirmed that this mix of two inhibitors can efficiently retard rebar corrosion in carbonated and chloride polluted concrete.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
