Abstract

The standard curing time of concrete is 28 days in order to guarantee the strength of the concrete. It is well known that a stable passive film can be formed on the surface of steel rebar in the alkaline pore fluid during the concrete curing stage, long before the steel rebar will be influenced by chloride ingress or concrete carbonation in the future. However, there is no consensus on the time conditions for the pre-passivation of the steel bars in the open literature. In this study, the growth process and characteristic evolution of the passive film formed on HRB400 steel rebar in a Ca(OH)₂ saturated solution, which aims to simulate the medium in concrete pores during curing period, were studied by a series of electrochemical tests (open-circle potential (OCP), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization curve (PDC)) and XPS. Results show that it will take 5 days to form a stable passive film on the surface of HRB400 steel rebar, and the passive film has a two-layered structure. In the initial stage of passivation, on the HRB400 steel surface a thin film mainly composed of Fe(II) products firstly formed, then on top of which, a film mainly composed of Fe(III) products would further form.

Key words: materials failure and protection HRB400 steel rebar passive film electrochemical tests immersion time
