Comment on We Finally Know How Ancient Roman Concrete Was Able to Last Thousands of Years

i’d be interested in seeing how using better concrete impacts overall costs and of course emissions. because the building ends up standing for a lot longer, the temperature isolation becomes very sub-par over time. that would increase total energy consumption compared to buildings that are frequently rebuilt.
but very promising.

Meh. Lime mortar absorbs and releases moisture. I wouldn't be surprised that roman concrete is much the same.
Don't get me wrong, I'm a huge fan, but that kind of thing isn't compatible with modern insulation. You end up with damp and mould issues in the walls.
Sure it works great in uninsulated stuff though.

Also we only see the few structures which survived. 99%+ did not make it 2000 years.

Spoken like somebody who doesn’t live where rooms would be intolerably hot without insulation most of the year.
