Abstract
Corrosion products on the rebar in concrete structures induce the tensile stress in cement-paste sticking the rebar. The elastic-dynamical formulation was applied to estimate the critical thickness of corrosion product around the rebar. The corrosion morphologies developing on the rebar are general corrosion due to carbonation of cement-paste and pitting corrosion by chloride ions. The induction duration for cracking initiation in cement-paste mainly depends on organizing the condition with starting corrosion.
