Das die Aktien von Heidelberg Materials (ehemals #Heidelberg #Cement) seit der Aussicht auf Neuwahlen um rund 70% zugelegt haben ist schon sehr dubios! #Fotzenfritz #CDU will morgen 500 Mrd. für #Infrastruktur haben + saß im AR von #Blackrock, die halten 5.5% an HM. #Finanzpakt oder #Insiderdeal?

Learned today:
Cement -making, which involves high heat, incurs 9% of the annual global CO2 emissions.
Roman #cement endured 2000 years, and counting.
"Ours" lasts merely 50-150 years.
Why is that?
Ours crumbles because little fissures are widened by rain water.
The Roman mix contains lotsa tiny calcium lumps. When fissures occur and rain enters them, it dissolves the calcium crumbs and this "dough" smears across the gaps. Case closed.

Heard in a curious podcast episode by a Noam Hassenfeld.

Also learned: when scientists drilled for sediment cores in 2022/2023 around Santorini and the submarine #volcano , the drill got stuck often, and 3 times, they had to use explosives to get it free. One reason: a Roman cement structure on the sea floor !
Thomas Ronge, cli-sci on this #IODP expedition, posted it yesterday on Bluesky.

The news cycle's dizzying. So something like this is helpful, even if I can't digest it all at once. The speed at which Our Putin is moving is shocking, but the Dems rolling over is devastating. NPR gives us in bullet points, day by day, this week's achievements in fascism.
