X-ray computed tomography characterisation of concrete
ABSTRACT
This video and related article demonstrate the effectiveness of the use of micro-CT for the characterization of microstructure and evaluation of concrete specimens, showing the data processing that can be applied to micro-CT data obtained from concrete. “Matrix, pores, and high density inclusions have been separated and analysed. This video presents the analysis performed on the porosity.”

A review of X-ray computed tomography of concrete and asphalt construction materials
ABSTRACT
Various destructive and non-destructive test methods are widely used in the field of concrete and other construction materials, but “the use of non-destructive X-ray micro computed tomography is still widely under-estimated and the capabilities not yet fully appreciated. This review summarises the successful applications of this technique to concrete and asphalt materials to date and thereby provides insight into the current capabilities and state of the art.”

The effect of loading duration on damage initiation in high-strength concrete
ABSTRACT
The underlying mechanism(s) that affect the rate sensitivity of the failure strength of concrete and other brittle materials is not fully determined. This study evaluates the experimental results that suggest that “the time-dependent failure process plays a significant role in the observed strength increase.” This analysis of the failure process in high-strength concrete (HSC) specimens demonstrates the evolution of specimen damage morphology as a result of intermittent uniaxial stress loadings.
