Re: 42" Pompeii - Northern Illinois

I get that. But I still recommend you keep it covered day and night until you start the block work.

GULF...Thanks on the photo's
Stonecutter… Don't know that I'm patient enough to wait two weeks to start on the block work I appreciate you comments I left it exposed for a few hours today and recovered. Seems to be setting up nice.

Re: 42" Pompeii - Northern Illinois

I covered with two layers of tarps last night?. Sunny today with highs in mid 50's. Rolled back the tarp and had condensation on the tarp and concrete. I was happy to not see ice.
The plan is to leave uncovered today an let the sun do its work and then recover late afternoon. Forecast for tonight is mid 30's

It would be better to just leave your tarps on full time for at least a couple weeks, to keep the moisture in the slab while its curing. This is not like drying out an oven dome, a concrete slab needs that moisture to cure properly.

Re: 42" Pompeii - Northern Illinois

I am struggling with posting photos?.. I have created an album in the FB photo gallery. When I insert them into a post I either end up with a thumbnail or Large photo?.. How do I post a thumbnail that will allow a viewer to click and see the larger pic?
Thanks

If it were me, I'd cover it and leave it covered for a few days. And leave the forms on awhile, too. Give it a good slow cure.

Re: 42" Pompeii - Northern Illinois

No, he should still cover it below freezing, because the outer layers will freeze, heat from the slab won't stop it.


Straw and a tarp is a cheap insulator and a lot of guys I know still do this. They sell insulating tarps too..under 50 bucks will get you one that will cover the slab.

I guess I neglected to say it should still be covered with insulated blankets being the best, common sense.

Re: 42" Pompeii - Northern Illinois

Thanks for all the comment regarding thermocouples and temperature control.
I'm thinking I might forego the thermocouples, as someone here mentioned WHEN they fail they will be virtually impossible to change.

Today was pour day!? I need to thank the family and friends that made short work of about 4,000 lbs of concrete. I was a little worried how things were going to go but all turned out well. Biggest challenge now is to keep it from freezing tonight (low temps 27F). I'm going to tarp for the evening?. Next couple of days should be in the 50's.
I will post the photos later?. I having a little trouble in that area.

Your concrete should fine at 27 degrees because it gives off heat as it cures. I would be a little concerned if it were to get down to the high teens.

Oh yeah, there is something saying about "who ever has the most gadgets or toys........." and I am as guilty as the next person. You should see all the gadgets in my "dog" house (the garage).

Re: 42" Pompeii - Northern Illinois

I've been following builds on this great forum and thinking about my build for a couple of years now. After waiting out the village permit application, approval from the homeowners association and finally the freezing temperatures and frozen ground, I'm excited to finally get started. Just finished drilling 5x10" diameter pier holes 42"deep, framing the base and adding the crushed rock and rebar tonight in the rain. The village inspector comes in the morning?.. Assuming all goes well and the weather holds, we will be pouring concrete on Saturday. I welcome any advice the experienced builders here can offer.

I will post additional photos soon.

Wondering if anyone has concerns in the northern areas with frost penetration and lifting and or shifting of slabs on grade. At the very least I would put a couple inches of rigid styrofoam under the slab to try to prevent this.

Re: 42" Pompeii - Northern Illinois

I Am,

Being an engineer, I thought that TCs were the way to go. I installed a couple in my dome one near the interior of brick and one near the exterior of the brick to measure heat saturation. All said and done, they work as design but in reality, I don't use them much now and just use the old infared gun or eyeball experience to cook. Nice gadgets but IMHO, use the money for some nice pizza peels.

Good advice here. I ditched the gun years ago. It has it's purpose, but after a while, you just don't need it.

But I'll not fault anyone for wanting another toy to buy......

Re: 42" Pompeii - Northern Illinois

For pizza all you need is to clear the dome and throw a bit of flour on the floor if you have a door and want to bake bread or roast just by a probe thermometer that will go through the door, about$25 all the rest is fun when new but you soon don't bother
