Can't show original post above it at the moment. It works on the other server. Followed the poster here just now. Probably in a few hours.

Link about Roman concrete, which is mindblowingly low maintenance:

This guy brings it very interesting! 🥰

The Pantheon would not exist without the concrete as it was in the Roman time.

Roman concrete was produced using lumps of volcanic rock and other aggregates held together with a mortar made with ingredients including a pozzolan (such as volcanic ash), a lime source (calcium oxide) and water.

Samples of Roman concrete contain small lumps known as lime clasts that are not found in modern structures.

The clasts were porous with cracks, which also suggested they were formed in a high temperature, low water environment.

The resulting lime clasts could have helped the concrete “self heal”, as water seeping into cracks in the material would dissolve calcium carbonate as it passed through the lime clasts.

Roman-inspired approaches, might be a cost-effective way to make better buildings.
