How Concrete Conquered Stone

Concrete is the most manufactured material in human civilization, but its takeover of construction wasn't a clean break. This episode traces the timeline from Roman concrete that still stands today — with self-healing properties we only understood in 2023 — through the 19th-century convergence of Portland cement, rebar, and a devastating earthquake that made concrete the default. We explore what was lost in that transition and whether stone construction could ever make a comeback. Episode #691532 — open it directly at myweirdprompts.com/691532
