Pore Structure of Cement/Pozzolan Composites by X-ray Microtomography
2005
Abstract Microtomography, a nondestructive X-ray analysis test, was used to study the pore structure of cement/pozzolan composites. The three-dimensional picture of the overall porosity was created by stacking together sequential slices of two-dimensional microtomographic images. This picture revealed all the pores above 5 μm in diameter, showing that the largest pore was 0.5 mm in diameter and that the volume of large pores was around 2% by volume.
