Abstract:
Concrete petrography is used to assess damaged concrete
in order to determine the probable mechanism of damage.
However, it is often difficult to say what mechanisms
caused the crack damage, since many deterioration
mechanisms produce cracks. This article describes a
hybrid imaging-finite element modelling technique that
can be used to help determine the mechanism of damage in
such cases. This application is intended to assist
concrete petrographers in assessment of degradation
mechanisms.
