Electrochemical behaviour of steel rebars in concrete: influence of environmental factors and cement chemistry
C Andrade, M Keddam, XR Nóvoa, MC Pérez… - Electrochimica …, 2001 - Elsevier
Four series of reinforced concrete specimens have been studied over 3 years exposure in a
100% relative humidity atmosphere. Addition of CaCl2, NaNO2, and a mixture of CaCl2 and
NaNO2 changed the cement chemistry with respect to an ordinary portland cement series of
samples used as reference series. The study, based on low-scan rate cyclic voltammetry
and electrochemical impedance spectroscopy, confirms previous results obtained in alkaline
medium, ie the redox activity in the rebar's oxides layer greatly influences the …
