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.
