Prediction of the penetrated rust into the microcracks of concrete caused by reinforcement corrosion

Consider a steel-rust-concrete composite consisting of a circular
cylindrical concrete cover and a coaxial uniformly corroding steel
reinforcement. Prediction of the amount of rust penetrated into the
microcracks of concrete cover from a set of data measured at the surface
of the concrete is of particular interest. The steel is assumed to be
linear isotropic and rust follows a power law stress–strain relation.
For the concrete, anisotropic behavior and post-cracking softening model
is employed. The formulations lead to a nonlinear boundary value
problem which is solved analytically. A key parameter β,
defined as the ratio of the volume of corrosion products inside the
cracks to the volume of the cracks, is calculated. With some efforts,
this parameter is also extracted from the available theoretical and
experimental studies for the purpose of comparison. The effects of the
mechanical properties of rust and concrete on β is addressed.
