Abstract:
This presentation focuses on how a project can be used to convey the complexities of rheological measurements on cement pastes to graduate students. In the first part of the project, the students are introduced to the rheometer, in the same way a technical salesperson would do. In groups, they measure the effect of constituent elements on a set of rheological properties, without advanced knowledge on the delicate intricacies of measurement errors. In the meanwhile, they learn about measurement errors and the advantages and drawbacks of data analysis processes. In part 2, they are instructed to re-interpret their measurements, identify the measurement errors, and repeat the measurement with the newly obtained knowledge. They discuss the magnitude of changes induced by correcting the errors in a group presentation, followed by an individual discussion on what they specifically took away from the project during the oral final exam.
