It's said that roman concrete contain volcanic ash and rare elements. If we can successfully locate and replicate the recipes, we can make modern structures much safer.

We do know the recipe… Chemist and scientists have analyzed it and broken it down with 100% accuracy and the composition is known… It’s not lost to time at all… It’s also a fact that there’s many different compositions/recipes that were used depending on available materials… Some of it has held up better than other Concrete and what is impressive is the Romans knew exactly what was best but obviously how do use materials available in some cases knowing that they were using inferior materials

There were many formulas for concrete. Many of which included burnt oyster or clam shells. Additives such as iron sand horse or ox blood, horse hair or flax. Volcanic ash nanotubes were used in underwater concrete. Crystalizing lime and Clay's. And marble aggravates.

They've figured the recipe out.

That recipe was found several years ago. It is also possible to make cars that don't fall apart. It is possible to build anything that could last 1000 years. It is not possible to make people less greedy.

For real think of the massive earthquakes Roman architecture has endured over time

We know the recipe. One of the main ingredients was salt water from the ocean. It works great, but limits what you can build because you cannot use rebar with it or else it will rust away.

I feel like it’s 3 things
1.)They survived after the flood and pre flood the world was as extremely advanced as the Bible says it was with giants and Noah’s ark.
2.) They came from another planet after the flood to restart civilization and teach or they’re in Antarctica .
3.) Aliens

It's probably human bones the people that died fighting in the Colosseum probably

by mixing the quicklime directly with the pozzolana and water at extremely high temperatures, by itself or in addition to slaked lime, a process the team calls "hot mixing" that results in the lime clasts.

It’s made from seawater,lime,vulcanic ash,blood and little stones.. Seen it in a documentary a few months ago. It hardens very quick,is stronger and lasts longer than ours,also doesn’t suck in water when dry ours up to 2cm,if i’m not wrong it even hardens underwater(they did a test in a aquarium) and a few other things that makes it better than what we use now..

It's called volcanic ash and large agrigate slake lime. Water triggers it to form microscopic crystalline structures. It's better with sea spray because of the salt

ive heard of some claims adding very fine ash to the mix will give a very strong result. next time im building something im putting together all the additives from diy shops, see what it looks like.

Horsecrap, we've used volcanic ash in concrete and we've built structures as permanent since the Romans.
Roman concrete has to provide resistance to both compression and shear forces due to its uniform material. Modern concrete is more resistant to compression but resistance to shear forces is provided by reinforcing it with steel.
Reinforced concrete is why we have been able to build thousands of structures bigger than the Romans ever dreamed.

Modern concrete is the mob recipe.
It’s not made to last cause they’d be out of business soon.

They figured it out. All this time, we've been trying to make it with slaked lime, when it's really a hot mix. The hot mix isn't as homogenous, leaving lime crystals scattered in the matrix. Cracks propagate toward the crystals, which then turn into calcite which heals the cracks.

I can put a sample through both MALDI mass spec to get the exact composition. And then through electron spectroscopy for surface analysis to see how the outer faces have reacted to outside elements over time. But oops! This has already been done - there is no mystery.
Concrete today breaks down because of rebar. We have concrete mixtures which contain various compositions beyond standard concrete which last as long as you like, when rebar isn’t used. So walls, sea defences etc. Rebar isn’t used for critical structure points in large buildings so we won’t see any sky scrapers crumbling due to this issue. Rebar is cheap and strong and fit for purpose in the applications it is used in. It’s not supposed to last forever.

Just to clear something up, the romans used a type of volcanic ash from deposits around volcanos in Italy. These deposits no longer exist in large amounts and it’s no longer profitable to mine what little remains to use in concrete.

Romans only used concrete in compression. They did not have rebar. Rebar rusting causes problems for modern concrete.

With TODAYS TECHNOLOGY, I find it Extremely hard to believe that THEY (whoever THEY is) cannot Reverse Engineer the cement to know EXACTLY what it contains!

They don’t want buildings to last thousands of years because it would put the industry out of business.
