calcium carbonate is still basic and even hydrogen carbonate is basic enough to be protective against steel corrosion
The Calcium Carbonate once dissolved in water will start to form the Calcium Hydroxide layer on the surface, thats the alkaline layer, and deeper in the carbonation creates acidity.
100% wrong, how come there’s more carbon dioxide inside than outside, you’re starting from calcium hydroxide and silicate. on the surface there’s some carbonate formation from carbon dioxide, but when it can’t get there calcium silicate forms instead. either way both are basic


coated rebar isn’t, it’ll always get dinged somewhere. stainless is expensive and the real available scalable option is either galvanized or sometimes basalt fiber, or glass fiber but i’ve not heard about it too much. the most important factor in slowing down corrosion is how thick concrete layer is on top of rebar, because concrete is very slightly porous and will let oxygen in, but the thicker that layer is, the slower oxygen gets to rebar, then the slower corrosion is, and this means it takes longer for rust layer to grow enough for concrete around rebar to fail due to swelling, because rust takes more volume than corroding steel
a bit of vinegar might strip zinc layer, but won’t do too much and definitely it won’t matter long term until most of zinc layer is gone. salt also promotes corrosion but this also depends on oxygen availability and won’t be too fast, it would only matter if there’s salt in concrete in large amounts


these things can corrode rebar slightly


concrete is calcium carbonate and silicate, both are basic. it’s also slightly porous but mostly waterproof by itself, doesn’t matter that hard in this application since there will be AC removing water from the inside 24/7 anyway


it’s more turbines, not sure if it’s the same site or another


your guess about what he actually did is as good as mine. gold salts are toxic and corrosive so it would be pretty obvious early on. small gold particles would occlude capillaries so that would be very obviois too. there is colloidal gold and gold nanoparticles are probably not very toxic. that discoloration could be some infection or irritation from whatever injected thing (not medical advice)


This will be good for renewables. Every solar inverter and wind turbine needs this stuff


they need something like two trillions for entire business to make sense, doesn’t mean that they’ll get it. zitron says the entire sector is worth something in tens of billions in revenue (not profit) per year


photovoltaic panels are just giant diodes you can run them in reverse and every panel gets that 0.6V voltage drop like any other silicon junction


Yeah they’ll make medbeds any day now. Or maybe it’s for their internal use only, because they’ll noticed bubble and don’t like what they’re seeing. I wonder if they’re foolish enough to vacuum up all data from companies that used their chatbots to come up with something hoping that no one will notice
Every single bit of that is so fucking stupid, they’re replaying crypto playbook 1:1. Spot an industry that they think they’ll manage in, then try to leech off of it in purest display of rentseeking imaginable, coupled with techbros folk belief that since programming is soo haard, then as they can do that they can do everything else too, all with no plan, no labs, no specialists onboard or faintiest idea what they’re doing
apparently it’s NFPA (american fire safety code) thing. these regulations might have been written when inhalational anesthetics were flammable. also keep in mind that people under anesthesia can’t move and that was also probably a factor
maybe it is for power cord specifically, and the same type is used for hospital equipment. some of (modern) anesthetics are powerful solvents but not particularly flammable. maybe it also has something to do with potential extra oxygen (or nitrous oxide) content in air


for the last three years and a bit, silicon valley has promised eradication of everything from writer to filmmaker as a career. after all this i don’t think that devs get to hitch their wagon to artists for sympathy points


still 84% to go


keep up, chinese are waay ahead of you https://en.wikipedia.org/wiki/Prayer_wheel tell the president about narrowing prayer gap immediately


That’s definitely not a sign that Softbank runs out of money


scams and propaganda


that destination could be still somewhere with access to stranded fuel and with access to other port, like oman, or they could perhaps truck it to yanbu and ship from there, but it doesn’t matter because price increase would probably need to be even bigger for it to make sense. facility would also need to run only on fraction of capacity, and there’s probably no point in that if you can’t export everything that’s made there. currently it might be damaged anyway. what i mean is, there are problems solvable by throwing money at them, but it’s probably not one of these
you see, you can be as wrong as you want to be. i won’t be teaching you middle school level chemistry against your will in a comment section. in concrete Ca2+ remains Ca2+, be it as hydroxide or carbonate or silicate and it cannot become reduced in normal concrete conditions and definitely it can’t be oxidized.
no it fucking doesn’t, this is what happens when cement is prepared in a kiln. near surface of curing concrete calcium hydroxide captures carbon dioxide from air, then this crust of precipitate blocks it from moving deeper. which is why the rest of calcium hydroxide reacts with silica forming calcium silicate, which takes more time and is responsible for late strengthening. before you lost plot i was talking about oxidation of steel rebar, and it depends on many things, but for regular carbon steel if there’s no oxygen then it’s much slower. and because concrete is not very permeable to oxygen, there are all these engineering requirements about how deep rebar has to be. anyway, a little bit of vinegar would be just neutralized by calcium hydroxide from concrete and won’t do anything, a little bit of salt would be diluted massively and also won’t do anything, hydrogen peroxide would decompose because anything will do that
