The Concrete Exercise is the last exercise of the Construction seminar in the first semester. The students not only learn how to pour concrete in theory, but also experience it for themselves. What does it mean to create a casting mold or formwork and what must be taken into account with a negative mold? How does the initially liquid concrete react over time? And how time-consuming is it to form something? Students learn in this exercise that every design has further consequences on the construction site.
