Opus caementicium, also known as Roman concrete, was an ultradurable building material used in the construction of countless monumental buildings that survived extremely harsh conditions for thousands of years. What was the Romans' secret? Heritage Daily has more: https://flip.it/ay8Q9N

"The #cement industry alone accounts for nearly eight percent of human-caused CO2 #emissions.

The Cambridge researchers approached the problem by looking at an industry that was already well established—steel recycling, which uses electric-powered furnaces to produce the alloy.

Instead of waste being produced, the end result was recycled cement ready for use in #concrete, bypassing the emissions-heavy process of superheating limestone in kilns."

We’ve been making good progress on the build. All that’s left to do before concrete can be poured is install filter fabric and our radon barrier (15-mil Stego). But, rain has stopped play today and the concrete contractor is coming Tuesday so Monday is going to be busy!

On Friday we bought a rock bucket for the tractor which is a game changer for getting big rocks out of our soil before we backfilled.

Etwas weiter. Grün und Beton. Aktivismus und Schaulaufen. Einige Orte sind noch vertraut und halten das Gestern fest. Andere haben still kapituliert und wurden von den Prioritäten dieser Zeiten überspült. Seltsames Gefühl: Moderne, Sauberkeit, künstlich-teure Leere.

What's not mentioned here is steel-reinforced concrete structures' lifespan - 100 years is an optimistic limit even for a quality construction. So all this shit will need to be torn down and rebuilt within 100 years. That's assuming that all these buildings in China are being made to top-notch standards which, from what I've seen on the Interwebs, is definitely not the case.

Später, irgendwo. Flieder über Beton, alte Büsche mit hellen Blüten. Junge Menschen in Freitagabendkleidung, geschminkt und parfümiert, warten auf die Bahn und sonstigen Anschluß. Weiche Wolken, weiche Farben über dem Zementgrau. Die Musik, die in den Kopfhörern verfängt, atmet alles an diesem Augenblick. Zweimal Repeat, dann rattert ein Zug über die Kreuzung, gegenüber weist eine Mutter hart ihre lebhaften Kinder zurecht. Türen klappen, ein Bus hupt laut und die Stimmung zerbricht. Es dämmert.

An MNC is the target of a civil claim for its role in #climateChange. It is #Holcim (which bought Lafarge in 2015, just after the bribes to the terrorist organisation "Islamic State").

The Cantonal Court of Zug has ruled "that the court costs and lawyers' fees will be borne by the State."

How it started… how it's going.

For a friends' house-warming gift, i made a house-number for them. As i was visiting for their birthday, i managed to give it to them and mount it for them (using hidden slide mounts which are quite cool). It's cast from concrete onto a cut piece of bathroom lino. The very slightly raised numbers were then painted (with Humbrol enamel).

(a few in-progress shots in the next post)

1/2

A concrete plaque with a number 14 painted on in white, mounted on a wall as a house number. The grey concrete has a horizontal wood-like texture. The numbers are very slightly raised and have a more bubbly broad grooved texture.

(Mittagswelt, Ortswechsel. Telefonate auf dem Sims, unten vor den Fenstern des Erdgeschosses. Verschiedene Wertungen von Dringlichkeit, und verschiedene Fähigkeiten, gerade in diesem Moment Konzentration aufzubringen. Kurierdienste parken in der zweiten Reihe, fluchende Radfahrer fahren Slalom, nebenan kehrt der Auszubildende des Hausmeisters Streusand in den Rinnstein. Wenig Überraschung in den Dingen. Noch ohne Kuchen, dafür einen Kaffee weiter. Weiße Wolken fangen Sonne in einem weichen blauem Himmel.)
