Despite all the chaos in the world, amazing innovation continues.
From Interesting Engineering:
Specifically, the concrete used for The Cube will be strengthened with carbon fiber yarn, which is made by extracting almost pure carbon crystals via a process of thermal decomposition known as pyrolysis. The yarn is then woven into a mesh that the concrete is poured onto before setting. As the carbon fiber doesn’t rust, the carbon concrete is also more durable over a longer period than steel rod-strengthened concrete. As structures can be much thinner due to the lack of steel rods — which often require more thickness to prevent water penetration — Henn says that this will enable “a future architecture where environmentally conscious design is paired with formal freedom and radical rethinking of the most basic architectural elements.”
