Episode 43: Geopolymers

Geopolymers are a unique class of materials that may offer a solution to environmental issues in the industrial sector including cement substitutes that produce only one-ninth of the CO2 as Portland cement. In this episode we talk about how they work and what, if anything, they have to do with the ancient pyramids.
