The Subject

This paper shows a teaching experience related to the use of computed tomography in the teaching of concrete for undergraduate students of the civil engineering degree. This experience reveals that computed tomography is a powerful tool to facilitate the understanding of all those aspects related to the microstructure of concrete, thus facilitating comprehension of the correlation between the microstructure and its macroscopic response. In addition, students showed a greater motivation and interest in the subject, which promotes better academic learning. A pilot test was carried out to evaluate the viability of these practices and to analyze the teaching impact of this activity. The results show that students were very interested in the use of new technologies in teaching and, more particularly, in the use of computed tomography. The students satisfactorily received the project. A greater motivation of the students in the subject was also observed, which resulted in better grades when compared with those of previous courses. The results reveal that the average grade of the students rose by around 8%, and a higher percentage of students achieved higher scores when compared to the previous five years.

Three Dimensional Images

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.
