Professor Kun-Hao Yu leads a sample class exploring the fascinating world of civil engineering materials—from everyday concrete, steel, and wood to advanced composites and polymers. You’ll learn how engineers design, test, and optimize materials for strength, durability, and sustainability, and see how hands-on activities like mixing and testing concrete connect theory to practice. The session also highlights exciting advances such as 3D-printed homes, robotic construction technologies, and pioneering research on “living” materials that can capture carbon, heal themselves, and adapt to their environment—demonstrating how innovation in materials could transform the future of infrastructure and contribute to a more sustainable world.
