What is the Future of Concrete in Architecture?

Interesting info about the sand! The same problem applies to fracking sand used for oil and gas extraction. There are few sites in the United States that can produce the sand with the required properties and it has to be hauled long distances as well.

The “Concrete Choreography” installation at Riom, Switzerland, presented the first robotically 3D printed concrete stage, consisting of columns fabricated without formwork. The hollow concrete structures are printed to allow materials to be strategically used, allowing for a more sustainable approach to concrete architecture.

“Sustainable” — there is that ridiculous word again. The idiot author uses it to describe a frivolous artwork installation. If these leftist kooks were truly concerned about “sustainability” they wouldn’t build such useless things in the first place. What’s the point of having sustainable frivolities?

Concrete has been used for 6,000 years without leftist nut jobs worrying about “sustainability.” It sustains itself just fine without invoking the Woke BS Du Jour.

With all the evidence about CO2 out there for ages now, what’s the big deal? It is not a pollutant in any way, shape, or form at normal atmospheric levels. It is plant food.

Same with my grandfather whose first real job was for Edison's son. He told me they called Edison Tommy. Also he said Edison was worried that the radio would hurt the phonograph business. BTW, grandpa was born in Russia, went to grammar school in NJ, quit after 6th grade, went to work supporting his family. And in his free time built transistor radios. By late teens is working for the Edisons in NJ.

Those were the last years of the great Industrial Revolution late 1910’s when Americans who were well-educated (6th grade back then was equal to college grads today), ambitious and ethical could take advantage of the Opportunity freedom gave them.

Remarkably, the article does not mention that concrete slowly reabsorbs carbon dioxide as it ages.

“(6th grade back then was equal to college grads today)”

Good point! IIRC, my neighbor dropped out of school in the 3rd grade to go to work at the cement plant doing odd jobs to earn money for his family.

I hate to say it but Grandfather when he wrote a letter had the eloquence and culture of the 19th c. That’s how superb schools were before John Dewey’s Progressivism swept thru in the 20’s and 30’s. Grandma from Prussia said her schooling (tutoring at home) was harder than mom’s NYC schooling in the 30’s which was superior to mine in the 50’s (Dick and Jane, no phonics, only 1 year of diagramming in Jr High.) Yet my schooling still included mostly well written textbooks in chronological order and reading Shakespeare and other classics throughout. Still my mom had to edit my papers, sigh.
