Roman Concrete gets STRONGER with Age

[stuffandthings]

Modern concrete does in fact get harder with time. But go off

They're also located in areas without harsh freeze-thaw cycles.

Pantheon is beautiful, but it has a hole in the roof. 😁

I’d love to see how this concrete would hold up to 40 ton truck driving on it

[bayareaartist]

modern concrete can be formulated to last 1000 years. It just raises the cost.

[Man-jezv]

Yeah and then the concrete making companies would go bankrupt essentially😂not something they would do i think

We use asphalt because it needs repaired more often they quit using cement on highways and roads in the 70s

[josephstabile]

If "Modern concrete deteiorates", how then is it that Portland Cement is "chemically similar"?
Do you mean "similar" like "close, but no cigar"?

[joelmccoy]

Engineered Obsolescence doesn´t allow for this.

[stevenfox]

its lie concrete gets harder with time

[xochj]

Roman concrete is only 20kPa. Stronger is a relative term here. The hardest it gets is basically as hard as limestone, vs Granite. It is simply not sufficnent for modern structures, roads, or even sidewalks.

[tinolino]

Because roman concrete is 4times weaker than modern concrete

[baltimorehoodboss]

Lasrs 2000 years...hmmm...too expensive

[markhottman]

They “Don’t make them like they used to”

[landornan]

Modern concrete can also be like 20 times stronger

[henryjanicky]

Similar with paint- today paint last up to 20 years or so ...in pyramids still in perfect condition

[edmanzetti]

Amazing- the G🔵Ds at work to help mankind

[zbk]

paroah pyramid concrete is more advance...

[abcfhdi]

they use rebar in modern concrete that rusts and expands causing the concrete to fail. they should just make better concrete or make a thicker base to support the weight like the romans did rather than trying to maximize square footage.

I liked this AI generated video until is turned into a shill for the concrete industry. Weird twist.
