@sagalensfilms: Roman concrete repairs its own cracks — the "sloppy mixing" everyone blamed was actually the secret, confirmed by a 2023 MIT study 🏛️ ancient engineering explained #history #historytok #ancientrome #engineering

Jack Reach around :

so why don't they start doing it

Tyrone's Domain :

Modern engineers care about money so they don't want something to last long.

OrgNintindo :

Yes but if you don't talk about the volcanic ash that part can't happen either. so they're concrete would be even more brittle so come on go with the rest of the story

Spencer :

Modern concrete lasts more than 50 years.

mariemaddock3 :

Not quite. It was the addition ➕ f volcanic ash that made the difference.

Damian :

If a structure lasts forever then building companies can’t keep taking our money.

milestuck :

and volcanic ash

Nickname :

that's so it keeps people employed

J :

not true it was just lime, slaked lime

Apricity :

modern just wants cheap materials and gain capital while cheaping out on everything 💀

Henfrido :

modern concrete doesn't last as long because it carries far FAR more weight on a daily basis. what do you imagine would happen if a semi drove on a Roman road.

CatMan1989 :

not true they used volcanic ash

Tony :

What about the lemons?

Allen Lift Crew :

The Mystery Chef :

Cuz take 100 years to cure 100 years to breakdown the concrete we use

🇰🇭 ស្មោះប៉ុណ្នឹងមិនល្មម🇺🇸 :

What the point of making things last longer while you can destroy it and rebuild it after 50 years and make more money…😂😂

J :

it was coarse but wet when built

Fernando_Carrasco_88 :

job security

cgrif05 :

Listen my cousin was a builder back then and he never told me about this. Roman lie

BRICKIN with FRANK :

If it wasn’t for modern engineering involvement those Roman buildings wouldn’t last.

Olgasandreva Isayenkova :

I feel like as a society we humans have gotten stupider. The Romans knew what they were doing ancient civil elations knew what they were doing. Why did the fuck did we dumb down?

Bushwacker11 :

BS
