I only found out last night that water makes the material crumbly (literally like the crumble on apple crumble).
I don't think that the issue is actually primarily the concrete weakening when exposed to water -- which does apparently happen -- but rather that the rebar internal to the concrete rusts.
You'll notice that nobody is complaining about "AAC" -- aerated autoclaved concrete -- but specifically reinforced aerated autoclaved concrete. The difference is the use of the rebar.
Granted, RAAC is probably used in places where structural strength is more important -- I don't know if a non-reinforced wall crumbling is as bad as a ceiling that's above someone's head.
The speaker in the video highlighted a new angle that I haven't seen before that I think is notable -- that specifically with RAAC, it's hard to tell if the rebar has been suffering from rust internally, because it apparently doesn't split the way regular reinforced concrete does.
Combine that with the fact that RAAC is particularly prone to rust damage to the rebar, and you've got a situation that theoretically shouldn't come up if the substance is protected from water, but if it does happen is prone to problems, is hard to diagnose, and has a catastrophic failure mode.
Yeah, sorry, but no. That's not slavery. If you're present in the country illegally and working illegally and could be returned home at any time, you may not be making as much as you would if you were present legally, but you are not compelled to work. You can always terminate working and return to the country where you are legally supposed to be. If you choose to be in Country A illegally and working there rather than in Country B legally and working (for less) there, that is your choice, and you are not being compelled to work.
£100 in 2020 is equivalent in purchasing power to about £125.60 today, an increase of £25.60 over 3 years. The pound had an average inflation rate of 7.89% per year between 2020 and today, producing a cumulative price increase of 25.60%.
That makes the nominal increase a decrease in real terms.
“In the context of the transition of the United States and Nato to an openly confrontational course of inflicting a ‘strategic defeat’ on Russia,
I do kind of want to point out that if Russia weren't off trying to annex neighboring countries in the first place, it wouldn't be in the position of having to worry about victory or defeat in said attempt.
In theory, yeah, I guess that that Brexit would permit for customs checks to be done.
But in practice, you've got the Republic of Ireland, which I assume will have free interchange with parts of the EU where the hornets are established, and I don't think that hornets are going to care much about the Northern Ireland-Republic of Ireland border, even if you guys and the Irish did come up with some kind of way to do checks there, despite the Good Friday Agreement.
And they managed to get into Canada, and looking online, it looks like Canada doesn't allow import of soil from anywhere other than the US, and we in the US don't allow it from anywhere at all.
I suspect that if soil restrictions weren't sufficient to stop them there, they probably also won't stop them from traveling from the EU to UK, even were such restrictions to exist in your case.
I generally don't add content unless it's really vital to understand the submission, just use the automated content. If I have comments, I'll leave them as a comment.
/r/Europe had really strict rules against editorializing submissions, and I think that that did a lot to avoid controversy. OP's opinions should be in a comment, treated like any other, and one should be able to upvote or downvote their opinions independently of the submission.
Most likely, one or two fertile queen hornets entered Canada via shipping packaging and created the colony that was discovered in 2019.
It’s easy for invasive species to travel this way. More than 19,000 cargo containers arrive daily at U.S. ports, and inspectors can only do random searches of shipping containers. One estimate suggests that just 2% of shipments are searched for evidence of invasive species. Many harmful organisms such as plant pests are intercepted, but some do get through.
It’s ya’lls fucking fault for expecting No Mans Sky to be the greatest fucking game of all time at release
Yeah, having read over a bunch of comments here, a lot of the comments that are unhappy about Starfield are basically people expecting it to be like No Man's Sky, or some people who just don't like Bethesda games in general. The ones that are happy tend to be people comparing it to earlier Bethesda games that they liked.
I really like Bethesda games, so for me, that's great. But I do also get that there are people who don't like Bethesda games, and for those people, being told that they're wrong and that they should like it drives them nuts.
I think a good rule of thumb is to probably expect Starfield to be similar to earlier Bethesda games, like Skyrim and Fallout 4. If you like those games, you'll probably like Starfield. If you dislike them, you're probably going to dislike Starfield.
But trying to convince people who really like Bethesda games that they suck or to convince people who really dislike Bethesda games that they're great is kind of not likely to work well.
In all seriousness, it may be that a lot of countries have something of a mess with RAAC.
Also, while RAAC may have been popular in the UK in public buildings for a span of some decades, it's not at all clear to me that it's not an issue in privately-owned buildings as well. I've seen a handful of articles pointing out that the British government is only acting on their own buildings. They aren't inspecting private-sector buildings.
The government has an extensive property portfolio, which was valued in March 2021 at £158bn and estimated to cost the taxpayer £22bn a year to maintain.
Some of the estate has been sold off the private sector – raising the prospect of expensive and extensive inquiries into the material’s use by private landlords.
The association has issued guidance for councils that says the concrete was “used by some municipal architects primarily in office and schools”. But it says it has been “found in a wide range of buildings, not all of which are still in the public sector”.
“The problem may be more serious than previously appreciated and … many building owners are not aware that it is present in their property,” it said.
I read another article that had some professor of civil engineering or something saying that it might be necessary to wind up treating RAAC the way asbestos is treated today -- that is, there is a legal obligation to know if it is present in a building if you own that building.

Beagles were bred to trail animals.
Labrador retrievers were bred to go after birds that get shot out of the sky.
You have a bunch of balloonists land what's basically the world's biggest bird in a field and the Labradors go bonkers and the beagles don't care.
I feel like all parties involved probably acted about as one might expect.
