Abstract

The internal cracking patterns of a series of small mortar specimens were observed using a technique called x-ray microtomography. The experiments were arranged such that three dimensional images of internal cracks could be made at several different points during the load history of the sample. This arrangement allowed progressive crack growth to be observed at micron-scale resolution in a single specimen. The specimens were loaded in compression. Applications of image processing and three dimensional visualization routines will lead to quantitative measurements of damage progression. The effects of particle packing arrangements and to a limited extent pore size distributions may be directly observed.
