Junior architecture major Mic Wilkins of Germantown, Tennessee, throws a concrete disk as part of a College of Architecture, Art and Design lab assignment. Associate Professor Alexis Gregory and Assistant Professor Silvina Lopez Barrera had Structures II and third-year collaborative studio students design and fabricate concrete disks.  Students tried to create disks light enough to be thrown far, but durable enough not to break easily. Students experimented with different concrete mixes, reinforcement fibers and additives for the concrete fabrication, as well as different fabrication techniques, including using digital tools such as a CNC-router and 3D printers.
