Abstract
A combined experimental and numerical approach for estimating the elastic modulus of reinforcement
corrosion products is presented. Deformations between steel and mortar were measured using digital
image correlation during accelerated corrosion testing at 100 μA/cm2 (~1.16 mm/year). Measured deformations
were compared to a numerical corrosion model that considers electrochemical, transport, and
mechanical processes, including penetration of corrosion products into a ‘corrosion-accommodating region,’
provided by the mortar’s capillary porosity, directly surrounding the steel. Comparing model and experimental
results provides an order-of-magnitude approximation of corrosion product stiffness of 2.0 GPa.
