Self Leveling Concrete

I poured self leveling concrete yesterday but the room is around 3-5 degrees celsius and I am unable to warm it beyond that right now.
The bag says it has to be at least 10 C.

Is it going to be fricked?

Will it even cure?

I scratched the surface with my fingernail and it comes off like sand. Maybe that's because it's only been 24 hours, but I'm scared that I permanently fricked it up.

Lets say it's not as strong as it's supposed to be, can I put another 1/2 inch layer of self leveling in the room at proper temperatures to improve the strength of the floor.
I am going to be tiling the area and putting a bathtub on it.

      I put a propane heater on and the temperature is probably around 10c now, but it was probably around maybe 2-5c the whole 24 hours yesterday, isnt that the most important period of time?

      as long as it doesnt freeze it should be ok just leave it alone nothing you can do for it now anyway

      >as long as it doesnt freeze it should be ok
      what about the first 24 hours when it was cold?
      I shouldnt be able to scratch some of it off, right?
      it might be okay after 2 days but I wont know until then
      how much strength will be reduced long term since it was below 10c during the first 24 hours?

        ok well whats the chemical formula of the mix what was the slab temp, air temp, rh, every 30 seconds?
        its either going to take a little longer or its completely fricked. stop scratching it leave it 48h at temp and then see where you are.
        if its a garage maybe you need to repour if its a closet maybe flatness is important but strength isnt.

    Wait so:
    1.you poured a self leveling compound on an existing cement slab.
    2. The temperature was too low for it to set, and this was like...24 hours ago
    3. You realised this and increased the temperature so it would set

    Quick google:
    >https://www.screedpro.com/post/tb001-applying-self-levelling-compounds-in-cold-weather
    >These types of products should not be installed after 2pm on a construction site

    where there is no internal heating and when ambient temperatures will drop below 8°C

    over night. If the ambient temperature is 8°C the concrete substrate temperature would

    be 5-6°C and at these low temperatures cement-based materials are put to sleep and

    thus severely affecting the curing process. In most cases the strengths will be greatly

    reduced but, in some instances, where the applied product has been put to sleep it may

    need to be completely removed and re-done.

    So it seems you're way lower than even the minimum temperature and it may not cure properly.
    You could wait and see, risk having to remove it. Or you could try removing it while wet, which would probably be a huge frick around as well.

      I can walk on it just fine. It's just that when I scratch it, some particles come off. Maybe that's because it's only been 30 or so hours?

        Generally, concrete gets harder over time.
        Even after 20 years, its hardness still increasing.
        My suggestion would be to give it a little longer to cure, and topcoat it with a sealer.

        >so does that help or hinder me?
        What I’m saying is that the concrete you’re using cure’s slowly as it is. Coupled with the cold, it’s going to cure pretty slow. At this point though, if it isn’t set I can’t imagine it ever will. At this point though I doubt it will hurt to give a few days. I’ve had pours I was sure wouldn’t cure and they did. Also you say the top comes off with a fingernail. It’s possible you fricked up the water to the point it bubbled on top but too much that it won’t cure. Mixes with plasticizer are much harder to dial in the water. I make concrete planters with it and I measure everything by weight.
        However if you used way too much water you may be screwed and colder environment would make it worse. Proper curing requires many variables you may have done too many improperly.

        Even after 20 years, its hardness still increasing.
        My suggestion would be to give it a little longer to cure, and topcoat it with a sealer.

        Concrete isn’t going to set over a long period of time. It has specific windows and if it doesn’t meet them in the first couple days, it never will. The reaction time varies somewhat but not that much. After 28 days it should be at or near 90% anyway so any extra hardening is negligible for most applications.

          Well at this point I can still scratch some sand off the surface but it's hard and I can walk and jump on it.
          Should I just say frick it and tile over it? What would happen over time if it didnt cure properly?

          I need to raise it up another 1/2 inch, could I just put another layer of self leveling over top?

          it will dry, but it may not properly cure. it will have poor adhesion and will be brittle. sorry mate, its gonna be bad, and will probably need to be redone.

          >and will be brittle

            >Well at this point I can still scratch some sand off the surface
            If you mean the very top as in maybe an 1/8 of an inch you may be fine. I wish I could tell you better but I only have experience with making planters. Definitely doesn’t translate to floors completely. I can tell you I’ve had the experience you described and concrete set just fine and was as strong as normal. I think it’s caused by water being a little off and/or air entrainment (which I forgot to mention). It technically makes the mix weaker but it may be strong enough for you.
            >but it's hard and I can walk and jump on it.
            Definitely a good sign, but again I don’t have experience with floors.

            >Should I just say frick it and tile over it? What would happen over time if it didnt cure properly?
            It’s curing “properly” now. The question is is it proper enough for the strength you want. You may have gotten all the variables close enough that it will be strong enough. I can’t really say unfortunately. I would try to add weight to it, maybe roll some heavy shit on it and see how it holds up. I’m no chemist but I can’t imagine it will degrade over time. I’ve never seen it happen even when I screwed up the mix. Like I said the question is the final strength.

            You can and especially if the surface of your first pour is rough (scratching sand off) it will bond pretty well. Definitely lay down some acrylic bonding agent first. Don’t let it look or get overly wet because then you’re going to screw your water ratio. You just need a thin film. Again remember you don’t know what the strength of the initial stab is.

            Standing back as someone who has nothing to lose either way, if I had to guess I would say as long as it seems to hold up with heavy shit on it and you can scratch the top of but get IMMEDIATELY down to a level where it’s firm and actually concrete, you’re probably ok. Please remember though that like I said I only know from making planters and the biggest one I’ve made is 100 pounds so I’m really no expert.

            So my question is…..you GAY

            Your mom certainly doesn't think so.

              this. I used this blue stuff and it’s amazing—I’m using the unused remainder as a waterproof glue since it’s got acrylonitrile butadiene in it. this stuff will also ‘lock in’ any sand-like shit on the surface.
              When I poured mine, there was this dusty/gritty layer on top and it was done correctly—they say you need to use the bonder between lifts.

              also consider laying down a steel mesh of some kind if you’ve got a full 1/2” to work with.

              if you can dig out a piece of the old floor, you can mix a tiny bit of the new and let it cure, then compare the two (try breaking it in your hands and whatnot) to get a feel for how the first layer cured.

    Temperature is very important for cement, mortar, grout etc.

    I would get some kind of heat on it and see if that will dry it out. If it was well mixed I don't see why it could not still work out.

    But if you get some hot heat on it for a day or 2 and it's still acting weird you may need to pull it all up. You can't put a floor over a surface that is acting funny.

    It's fuked. We pour self leveling all the time at work. Needs to be clean warm and use lots of primer. Don't pour before primer is dry or it will make soft spots or flake when weight is apllied. Pour when it's cold and it takes to long to cure and becomes soft sand.

    Just keep it heated continuously from now on. Either it's fricked or it isn't, you'll only know after at least several days. Given that it's already in, there's no benefit in pondering over it. If it's still crumbly/sandy after a week, then it's probably fricked. If not, wait a couple of days more for good measure and tile over it.

    I'm looking for a concrete simulate to lay over a plywood sub floor. Just looking for the effect, I doubt the floor is strong enough to handle the weight of real concrete.
    I can find vinyl tiles as big as 32x32" but would prefer a single seemless sheet. I found one vendor with linoleum sheets but priced at $6/sqft, very high for linoleum. Anyone know any vendors that might have what I'm looking for?

    You should be fine eventually. However, the cure will be shitty and long-term it will show you fricked up. Perhaps you can put a skim coat or rent a time machine and go back to before your mistake.

    Op here. So it's basically crumbling away anywhere I walk. You think it's safe to just tile over it? Will the tiles keep it together?

    Have you thoroughly soaked the slab before pouring your concrete?

    Actual concrete inspector here. Concrete will be ok as long as it didn't freeze. The strength comes from a process where tiny crystals form in the mix locking everything together as it dries. They will still form in cold weather just not as fast. If I was OP, I would ensure the slab was constantly moist for a period of at least 7 days, mist with a garden hose every day, if it the mix dries out too soon while the weather is cool you will not get as good of crystal formation.

    hey guys update, I put 5 heaters and the temps are about 180f, it's a bit hot in there but will probably help the concrete dry, house is smoki a little, so i clogged the sinks and ran water, nice and wet now
    softened teh concrete right up and now i can comfortably lay in it, like a waterbed very nice
    Also painted over the concrete with lead paint cuz lead is a metal and metal is hard it will keep it together
    im a bit dizzy and sleepy now so i will take a nap here on the floor
    thanks 4 all the hleps u guys are grate

      I put peanut butter on it as mortar and tiled it.
      The tiles slide around a bit, but it's pretty tolerable.
