Description |
Surface treatment on the concrete surface using sealers reduces the rate of permeability
of chloride and moisture through the concrete. The delaying of onset of corrosion is evaluated for
surface treated and untreated concrete using electrochemical techniques. After conducting rapid
chloride permeability test (RCPT), using Nernst–Plank equation, the diffusion coefficient of chloride
(Deff) is calculated. Substituting threshold chloride concentration of rebar (Cth) from cyclic
polarization test in the ficks second law, the time to initiation of corrosion (Ti) is arrived. From
the results it is found that the treated concrete with alkyltrialkoxy silane sealer delays the onset
of corrosion by four times than that of untreated concrete.
