The Romans did not have unions interfering with construction.

Unions will never allow for the original method to be used. Building roads that last? Unthinkable! There goes one of their methods of keeping lasting employment…

Would love to see this translated into a set of easy-to-follow instructions. I’m building a house soon, and I want to make it as durable as possible.

Smithsonian had a great article on concrete years ago. I found this article interesting.

I looked at the article too.

From the introduction:

“... method to reduce cement’s carbon footprint (which accounts for up to 8% of total global greenhouse gas emissions) ...”

What do greenhouse emissions have to do with the subject of the report? Nothing.

And it’s unbelievable that more recent concrete research hasn’t discovered those long lasting concrete formulations. I’ll bet today’s concrete experts know all about the use of ash, quicklime, and a lot of other ingredients.

The researchers behind the report used “a multiscale correlative elemental and chemical mapping approach”. Wowee!

“I’m sure almost nobody commenting has ever heard of a flash set.”

Didn’t seem to stop the Pantheon.

And despite the lack of rebar-type reinforcement still going strong.
