Abstract:
Concrete has long interacted with nature—from Roman seawater concretes that mineralized in situ to oyster-encrusted breakwaters and vegetated revetments. These precedents suggest moving beyond “resistance only” toward resilient structures that cooperate with living systems. This talk outlines a paradigm of structural–ecological symbiosis using ultra-high performance concrete (UHPC) as the platform. UHPC’s strength, toughness, and durability enable slender sections and protective shells that preserve safety while creating room for biofunction. Near-term work targets: (1) bio-receptive UHPC and surface morphologies with tuned roughness, porosity, and nutrient microchannels to support benign biofilms, lichens, shells, or engineered mosses; (2) fiber/lattice exoskeletons that mechanically support climbing vegetation or root mats without sacrificing cover or durability; and (3) quantifying growth-induced actions—root pressure and biogenic mineralization—on cracking, stiffness, transport, freeze–thaw, abrasion, and fire. The aim is practical: nature-positive UHPC elements that protect people and infrastructure while inviting habitat.

CI4802ModernSkyscraper
Rachel Schick and Sidra Dahhan
“The Modern Concrete Skyscraper" exhibition at The Skyscraper Museum in New York, NY, USA, retells the history of the high-rise through the lens of reinforced concrete. CI staff were toured through the exhibit, gaining insight into the curation process; the inspiration, goals, and themes behind the exhibit; and its reception.
