Taryn Simon collaborated with Russia’s State Atomic Energy Corporation (ROSATOM) to prepare a work of art made from nuclear material. In the year 3015, approximately one thousand years after its creation, a black square made from vitrified nuclear waste will be permanently displayed at Garage in a custom designed void that has been integrated into the new museum building.
Depends on what the concrete is made of.
Not having rebar means it’s going to be significantly more stable over time since you no longer have to worry about de-alkelineization (spelling is hard), and rust causing expansive forces inside the concrete and cracking it.
The chemical composition of the concrete will probably be improved over time as budget allows, increasing its longevity quite significantly.
Ancient structures used iron pins and bars, but they were covered with lead to protect them from rusting, plus lead is also plenty soft enough to not damage concrete.
Yes we all know lead is toxic, so just don’t lick the lead covered pins/rebar during construction 👍
Mmmm, lead-covered-rebars
