Put a couple packets of sugar in about two quarts of leftover bag concrete once just to see how it went. Initially it acted like it had plasticizer and got loose and wet again. A day or two later it was acting like it had just set and a month later I could still crumble the edges off with my thumb.

Problems with using this for sabotage. Any serious project will have an engineer checking every truck and it will not pass unless the person adding water at the plant was in on it and did some very good calculations. Then the saved samples would immediately give them away in the investigation. During and after the pour there are too many people watching. I would have to say putting brown sugar and salt in the footing trenches the night before it’s poured or spraying (big puddles will get drained) a solution on top of the plastic to look like rain or dew.

This doesn't work

[-] irelephant@lemmy.dbzer0.com 31 points 14 hours ago

This gets posted bimonthly around here

[-] Zirconium@lemmy.world 10 points 12 hours ago

It could be possible this post is part of some disinformation campaign

[-] StupidBrotherInLaw@lemmy.world 6 points 10 hours ago

It sounds good and some people share such things without critical thought. It's like adding sugar to petrol - it doesn't actually do anything beyond possibly clogging the fuel filter, but the promise of such easy means of destruction appeals to some.

[-] this_1_is_mine@lemmy.ml 10 points 13 hours ago

It doesn't fully work if you add enough sugar it technically would but all it will do is just slow the setting process

[-] AnUnusualRelic@lemmy.world 1 points 24 minutes ago

It might work if it's half sugar and half concrete.

[-] irelephant@lemmy.dbzer0.com 1 points 1 hour ago

The concrete is actually stronger once it sets if you add sugar to it

[-] chaogomu@lemmy.world 12 points 13 hours ago

Yup, people who drive concrete trucks often keep a couple liters of soda to add to the load if they run behind.

Keeps it from setting up in the truck, but that's it.

[-] Famko@lemmy.world 25 points 12 hours ago

IIRC from my material science course, if you really want to fuck up a batch of concrete, you should use salt instead of sugar, cause it'll crack the concrete with every freeze and thaw cycle.

[-] rhombus@sh.itjust.works 1 points 4 minutes ago

It’s the same as with the sugar, you need a lot of it to make much of a difference. Unless it’s reinforced concrete, then the salt in the water will corrode the steel rebar and that will definitely cause cracking.

[-] phoenixz@lemmy.ca 3 points 9 hours ago

How much wall does one tonne of concrete give you? Seems like you need tonnes of sugar to properly do this

[-] Gullible@sh.itjust.works 9 points 14 hours ago

Why does this work, exactly?

[-] Nora@lemmy.dbzer0.com 43 points 14 hours ago

It doesn't! (ish)

Sugar can slow down the hardening of concrete, but this is too small of a concentration and even if you do increase the concentration it still hardens which (depending on the application) does not ruin it.

[-] Jiggle_Physics@quokk.au 18 points 14 hours ago

Yes from what I can find, depending on the type of concrete, it takes 4-30lbs of sugar per ton. The point is not to keep it permanently plastic, it will set, but its structural integrity is greatly compromised and it will crumble under stresses far, far, lower than it will need to deal with.

[-] Mouselemming@sh.itjust.works 3 points 12 hours ago

So now you have a prison which will catastrophically collapse upon the prisoners?

[-] Nora@lemmy.dbzer0.com 10 points 11 hours ago

Well no because the other part of this that isnt talked about is... concrete is heavy as fuck, and one ton of concrete is basically nothing size wise. Its more like you have to throw 200lbs of sugar in every truck that arrives at the job site, often with many many trucks.

[-] anomnom@sh.itjust.works 1 points 6 hours ago

That was the red flag when I read this. After letting a few footings for a porch I started till captures how many tins must go into a garage floor slab, let alone a prison in billionaire bunker.

[-] Jiggle_Physics@quokk.au 1 points 12 hours ago

The structural issues would mean they could not get to that point in construction

[-] Nora@lemmy.dbzer0.com 5 points 14 hours ago

There's like a thousand caveats to this though just as an aside. If someone realizes the concrete is tampered with, they're probably tossing the whole batch. It's better to be safe than sorry and they probably don't have time to wait for the lab report on what got added to the mix without their permission.

Not that I'm recommending that people do this, but if you wanted to fuck up concrete I'd think going for a compound that makes it cure faster would be the way to go. Too fast leads to more heat which leads to fractures in the concrete from the intense heat.

[-] chaogomu@lemmy.world 5 points 12 hours ago

Salt. Salt will completely fuck concrete.

There were Chinese construction companies that cut corners and used beach sand instead of more expensive river sand.

The buildings the made are all called Tofu towers or something similar, because you can walk up to the ones still standing and pull chunks off, like they were made of tofu.

[-] Jiggle_Physics@quokk.au 4 points 12 hours ago

This works too. You keep forcing them to toss materials, and delay the building of the prisons.

[-] anomnom@sh.itjust.works 3 points 6 hours ago

So you really just need a few huge empty bags of salt/sand/rice/etc, then get caught sneaking out of the mixing plant.

[-] NCSK@fedia.io 5 points 14 hours ago

what if I drink the concrete before it hardens? will that work?

[-] fyzzlefry@retrolemmy.com 1 points 7 hours ago

The current HHS is probably on board.

[-] Nora@lemmy.dbzer0.com 4 points 14 hours ago

I'm not a doctor but I don't recommend it.

[-] mindbleach@sh.itjust.works 2 points 13 hours ago

They definitely won't be able to use it, and you'll have nothing to worry about.

[-] Septimaeus@infosec.pub 3 points 14 hours ago

Depends. How are your calcium levels?

[-] bacon_pdp@lemmy.world 0 points 14 hours ago

When sugar is added to Portland cement paste at the onset of mixing, hardening may be delayed indefinitely.

Sugar is added to concrete to delay delay curing and improve compressive strength but after 0.06% sugar by weight, compressive strength starts to decrease and after 0.08% sugar by weight setting times dramatically increase.

If you add two pounds of sugar to literally one ton of concrete, it will ruin the concrete and make it unable to set properly. This was used by the French anarchists to resist prison construction.

[-] Cethin@lemmy.zip 9 points 9 hours ago

I'm assuming this is AI generated misinformation that pulled incorrect information from all the reposts. Please stop doing this. AI doesn't know anything and only repeats stuff that is said frequently, which is often wrong, like this case.

[-] saltesc@lemmy.world 2 points 11 hours ago

I'll believe it when me shit turns purple

[-] fyzzlefry@retrolemmy.com 1 points 7 hours ago

And smells like rainbow sherbert?

[-] Skyrmir@lemmy.world 1 points 10 hours ago

You'd need at least 10lbs of sugar per ton of concrete, probably closer to 40. If it's a full truck it's probably around 800lbs of sugar to ruin the load.

[-] Impractical_Island@lemmy.world 0 points 9 hours ago

You can pour sugar in a car's gas tank, it will really fuck up the car. Go ahead, test it with your neighbors. They will be pissed af, but as long as you don't have a flock camera around, just walk up with a mask n shit and they ain't knowing whst you do if you don't do what is that you be, obviously.

Is this to stop the Suburban Rail Loop for some reason?

Flippant Anarchism. A lighter take on social criticism with the aim of agitation.

Post humorous takes on capitalism and the states which prop it up. Memes, shitposting, screenshots of humorous good takes, discussions making fun of some reactionary online, it all works.

This community is anarchist-flavored. Reactionary takes won't be tolerated.

Don't take yourselves too seriously. Serious posts go to !anarchism@lemmy.dbzer0.com

  3. Absolutely no right-wing jokes. This includes "Anarcho"-Capitalist concepts.

  4. Absolutely no redfash jokes. This includes anything that props up the capitalist ruling classes pretending to be communists.

  5. No bigotry whatsoever. See instance rules.

  6. This is an anarchist comm. You don't have to be an anarchist to post, but you should at least understand what anarchism actually is. We're not here to educate you.

  7. No shaming people for being anti-electoralism. This should be obvious from the above point but apparently we need to make it obvious to the turbolibs who can't control themselves. You have the rest of lemmy to moralize.
