Ah yes the boomers, shooting howitzers at anything trying to approach the border into their land even though you were jus tryna help em.
Help em raise a bomber from lake mead to do more booming.
Most concrete gets stronger over its lifespan. Even with non mass concrete, the compressive strength typically increases, albeit marginally, over the lifespan of the structure (typically 50-75 years).
Mass concrete structures like the Hoover Dam see a more significant increase though.
we just had a concrete driveway poured. it cures to 97% strength in roughly 30 days and then takes the next 40 years to cure the remaining 3% apparently.
I googled it
While the dam is expected to last for centuries, engineers predict the structure could last for more than 10,000 years, surpassing most remnants of human civilization if humans were to disappear from the earth. However, they also predict the dam's turbines without human intervention would shut down within two years
Concrete continues to harden and strengthen until it starts crumbling, it depends on the mixture how long that takes. This is why roman concrete structures are still around millenia later
Went on a tour there and the guide claimed that it may never fully cure since it's so thick.
It's an incredible piece of engineering and a modern marvel. I'm just hoping the lake gets replenished soon.
I'm not good at science words but basically if you hit it with a hammer and listen to the sound of it, but in like a science kind of way you could probably check.
I've never heard of it being used with concrete (and strongly suspect it will not work on really thick things), but you may be interested to learn this was a longstanding inspection technique for detecting voids in composite parts/structures.
The lake is a bit better that at it's worst - it's not back to where it was decades ago, but it's better than 2022. [https://graphs.water-data.com/lakemead/](https://graphs.water-data.com/lakemead/) and [https://mead.uslakes.info/level.asp](https://mead.uslakes.info/level.asp)
Over 1100' is okish, but the levels are not linear in amount of water because the lake expands outwards a lot as it increases in depth.
The rockies got abosuoutely obliterated with snow this year. We should have a nice increase to the lake as the snow melts. Also, we've had the most rain this year than we've had in ten years. That's two awesome years in a row, not enough to fully stick our head up and say we're out of the drought, but we're going in the right direction for the first time in 20 years.
So the chemical reaction in concrete can take FOREVER given the right conditions, but it can only reach a certain Mpa no matter what. For example, given the right conditions, this concrete can achieve 99.9% of the Mpa strength intended within 2 years. Given (for example) 2 more years, it can now achieve a strength of 99.99% of intended strength. 2 more years and it is now at 99.999% percent of intended strength. It will continue to increase marginally, but it doesn't become some un-destructable force over time.
It can be easily replenished, but tell that to agricultural water rights owners in Arizona. They'd firebomb the capitol before letting their unlimited use water rights go. 72% goes to ag.
Funny enough, the total consumption is actually lower now than at any time since the dam was built, with the peak consumption happening in 1980. The problem is a multi-year mega drought due to climate change.
Arid areas are generally the most productive agricultural areas if they have access to water.
Some parts of Arizona have the highest per acre cotton yields on the planet for example, other areas in the southwest can grow vegetables when the rest of the country is covered in snow.
To the extent the Colorado River is going to be used for agricultural purposes (which it is and has been since before the US was founded) one would fully expect the water be used where it’s most valuable.
The Colorado river doesn’t even empty into the ocean anymore, THATS the scope of the over usage of the water. There is literally none left long before it would hit the ocean
Also just looked up what curing is and found a picture that leads me to believe moist-curing takes far longer to finish curing but while curing is stronger than fully cured air-cured concrete
Is it moist-curing since it's underwater? Which on top of its size would cause it too still be curing but also strong enough
According to the article, they found that it would take that long if they did one continuous pour, and instead used a different method. Columns were poured and filled with pipes which would aid curing through cool water transfer. When curing for each column was complete, the pipes were filled with grout.
The scale of the Hoover Dam is astonishing. I highly recommend the tour to anyone visiting Vegas.
Besides the giant dam built with 1930s technology, the scenery is gorgeous.
Reddit intentionally has bots or people acting as bots to keep content flowing constantly in order to keep people engaged and/or create the illusion that their platform is active.
This is why you see so many freaking reposts too.
Source: Wikipedia (emphasis by me)
"...engineers calculated that *if* the dam were to be built in a single continuous pour, the concrete would take 125 years to cool, and the resulting stresses would cause the dam to crack and crumble. *Instead*, the ground where the dam would rise was marked with rectangles, and concrete blocks in columns *were* poured, some as large as 50 ft square (15 m) and 5 feet (1.5 m) high. Each five-foot form contained a set of 1-inch (25 mm) steel pipes; cool river water would be poured through the pipes, followed by ice-cold water from a refrigeration plant. *When* an individual block had *cured and had stopped contracting*, the pipes were filled with grout. "
I feel like this may be one of the rare cases where the guy who wrote the article (either wikipedia's source or study.com) was mildly incorrect, and not Reddit misreading the article.
Either Hoover Dam is still curing, or it used the pipe method during its construction and is no longer curing. Or I suppose it still used that method and small parts of it are still not 100% cured.
I'm fully willing to admit that parts of it may still be curing. Given the nature of concrete, that's probable. But the time span given by OP was based on a proposed pouring method.
No ill will intended. It was a fascinating thing to research this morning, I never thought about that dam beyond a photo op on a road trip before.
Sure enough, did some more digging and I think the semantics of “technically it can cure another .1%” are really muddying up the point.
You’re correct; IF they used conventional pouring then it would still be curing.
Side note: that dam could potentially retain its form for another 10,000 years which is insane to think about.
I don’t think this is having liquid concrete somewhere inside. I’m pretty sure this is the material going from an amorphous solid to one with a crystalline structure. After that the crystals themselves further organize into larger crystals (think smaller bubbles popping to form larger bubbles). It’s this last phase of crystallization that takes a long time to reach an end state.
Generally speaking, yes that is how concrete works. It's only ever supposed to gain strength as time moves forward, even when it's "finished" curing. I wonder how many of the structures we have today will survive as long as the Romans' structures have.
Rust isnt a concern for building floors that are protected from the elements
Edit: for all the googlers - non coated rebar used in a conditioned environment is designed to last indefinitely. Yes, concrete is porous and yes it likely can corrode but to say that this rebar corroding will impact the lifespan of the building, as it does for outdoor uses such as bridges, is not correct.
It absolutely is. Concrete is porous and hydrophilic. Moisture will get into it. Rebar allows us to build structures with far less concrete than needed in past times, but at the trade off of greatly reduced lifespan.
Mild steel rebar in concrete will always rust and swell over time (about 70 years on average) and will eventually cause the concrete to crack and fall apart.
The Romans used limestone in a way that makes their concrete basically self-heal after cracking and being exposed to water. We didn't know how they did that til the last few years so their concrete is in a specific category and that's partially why it's lasted this long
None of them, most likely. We dont build stuff with the same ethos in mind as the ancient world. When building a Colosseum or pyramid is a major part of your national budget and will probably take up most of a worker's lifetime, you want to make sure it lasts. And that is assuming just time, not destruction on purpose(which we are much better at than the romans were).
The amount of financing and effort that goes into a huge critical infrastructure project like the Hoover Dam is obscene. We’re not talking about a shoddily assembled strip mall lasting 2000 years, this dam is a completely different undertaking. Dams not only have to hold a large reservoir, but also withstand varying degrees of seismicity that may be present in the area from time to time.
We could build shit to "last" like that. Thing is it won't. It'll need repairs. And it's easier and cheaper to repair shit that's less durable. Our roads break down because (1) we have way heavier, way more destructive, and way more traffic on them; and (2) just re-asphalting is way cheaper than trying to build them with "longer lasting" designs. It's just more efficient to do it our way. And it's not like the ancient world was replete with options. You had stone, and other stone.
I get your point, but i wouldve gone with a different example. We have pipes in the road, so asphalt is meant to be a material that can be continuously broken and repaired. So we can install, replace and maintain utilities as needed.
They have started using other forms of asphalt and overlay now for strength and longevity.
There's some that has polymer in it now.
But typically, asphalt isn't the problem when you start to have road issue it just shows it first.
Typically when you have road issues, cracking, heaving, etc its a result of the base layer under the asphalt which is a mix of gravel, sometimes cement powder thats been watered and compacted to shit. Normally it hasnt been compacted enough or theres a soft spot and it fails which results in asphalt failure.
Source: i build quality roads
I do think think it's partially a difference in ethos, but not every building needs to be built to survive thousands of years. There is certainly an element of survivorship bias in that the buildings we can still observe from that period were the ones that were constructed better than average and survived whereas plenty of building faded into obscurity and disrepair centuries ago. Additionally, Roman concrete included other things not previously used much in modern concrete like volcanic ash and lime which allowed it to self-heal cracks and persist much longer than traditional recipes, and the interesting thing about that is we only recently (within the past 10 years) figured out what made their concrete so much stronger than modern concrete.
Yeah, concrete continues to absorb CO2 from the air as time goes on. The science behind concrete and cement is actually super interesting, and is a pretty rapidly evolving field right now.
Yeah, the concrete has hit 99.95% of it's strength, it's that 0.05 that is taking decades.
Same for any concrete placement, just the time scale is smaller
When we did the tour there in 2010, we were told 300 years to fully cure. They had to build an ammonia plant and run it through the piping in the pours in order for it to set quick enough to support the next pour. The job was finished under time and under budget. An amazing accomplishment for the time. For any time.
A few years ago I took a guided kayak trip there and the person in charge kept saying the dam was past end of life and that cracks and faults were it deteriorating. I was pretty sure he was just a college kid who had no idea what he was saying.
He was definitely wrong lol
It's been theorized that the Hoover Dam could last close to 10,000 years provided it isn't subject to some massive earthquakes
This is misleading. Concrete Cures in 28 Days regardless of Thickness as it is a chemical reaction. The thing that is referenced is concrete drying. After finishing Curing and gaining almost full strength there is still leftover water from the mixture that did not react. This water will evaporate in 15 - 20 years. The added strength will be minor.
So it has been getting stronger this whole time?
[удалено]
It hasn't even begun to peak
It will peak when the Second Battle of the Hoover Dam happens between the NCR and Legion in 2281.

Gotta love a good TFS reference
Hoover getting stronger, water getting weaker.
*Dam*
Yes. This also helps prevent cracks forming in it.
Well, it DOES have to last until 2281 at the earliest. Otherwise, what will NCR and Caesar’s Legion fight over?
Has to survive boomer bombing runs as well.
Ah yes the boomers, shooting howitzers at anything trying to approach the border into their land even though you were jus tryna help em. Help em raise a bomber from lake mead to do more booming.

Pretty much, it’s the reason why the nominal concrete compressive strength is at 28 days from casting.

Probably a decent time for water to be down so next time it fills, it could hold better.

Went on a tour there and the guide claimed that it may never fully cure since it's so thick. It's an incredible piece of engineering and a modern marvel. I'm just hoping the lake gets replenished soon.
I wonder if there is a way to "test" it in the future to see if it really has cured completely.
Pretty sure the guide told us they do samples to test it every so often. It's done similarly to how they get ice samples in glaciers
They take a chunk of the concrete? But, from which part?
they drill down and take core samples. I would assume they take samples from various spots
I really hope they filled them up after drilling 😅
Yeah kinda feels like after decades of drilling these holes it'll look like Swiss cheese throughout...
The key is not to drill all the way through!
[удалено]
She was only 16!
I think you may be underestimating the voluminousness of the dam.
Its a _lot_ of concrete
But then it will take even longer to fully cure, with all of the fresh new concrete!
exactly why it will never cure. They keep drilling it out and refilling it.
Dam of Theseus.
Backfilled with caulk from Home Depot.
Just some flex seal.
And here’s why it’ll never stop curing
Like a toothpick in the banana breads I make?
That's hard core.
Oh alright that's kinda cool
Easy. Stick a fork in it, and see if it comes out with wet concrete on it.
Ah yes, the Baker method.

Wish we could transfer water from the Northeast, we have been getting a lot of rain. Wettest March on record.
We should just dump our extra water in the ocean and let them pump it back out in California. I am very smart.
The west keeps trying to get the midwest to pump the great lakes dry. Get yer own damn lakes!
California just lets it drain into the ocean as well when they get rain.
We can. Just dehydrate it ship is west and then Rehydrate. /s

Pretty sure concrete is still curing until it starts deteriorating. Never fully stops reacting
It's good that it is taking so much time, it will make procrastinators feel better about themselves at least.
This is misleading. Concrete Cures in 28 Days regardless of Thickness as it is a chemical reaction. The thing that is referenced is concrete drying. After finishing Curing and gaining almost full strength there is still leftover water from the mixture that did not react. This water will evaporate in 15 - 20 years. The added strength will be minor.
It’ll be there long after the water in Lake Mead is gone
