We only run calcium when it's too cold to cure on it's on. Sitting in my truck right now and it's 36 degrees. Were pouring a few jobs this morning and I think running 1% non chloride in all of it.

CHASMAN9 said:Agreed, I've got over 36 years in building experience with everything from a custom single story Dog run to a $21m 2600 Highland rd condo's and want to understand what I have been doing wrong all this time? A concrete block has a much higher chance of freezing and cracking due to it's porous nature whereas a well poured monolithic slab will not have the same properties. Type S mortar has a psi of approximately 1500 and the block has a 1900 psi breaking strength whereas concrete has a 3000-3500 psi breaking strength and cures all at the same rate. Now if you introduce Calcium into the mix, it will harden faster in cold weather but also has a higher chance of cracking. To help alleviate that, you can add fibermesh which is fiberglass strands that are added into the mix to help strengthen the slab after it has been cured. I could be wrong on this, but possibly not.

And I'm also in the East Tennessee were ground is not flat. Couple of reasons why I said what I said number one being siding factor of where I mostly build your not gonna flat ground. It's also a possibility if you don't have the money to do a full slab when you build your shop you could do footers and Block come back at a later time and pour your floor. Never said you didn't thing wrong. Every area you build in is different. I see a **** ton of builders here have to bring in dirt or dig out and back feel to try and make a level place for slab. I can't tell you how many structures I've seen with a poor pad over loose fill dirt. I will always stay until I hit native guard before I do footers or a slab sometimes it's impossible to do a slab therefore we must dig down and will have some deep footers and Block work. Like everything else weather you're building a dog run a shed a buggy everybody has their opinion. I agree hundred percent with your post but around here it's not possible to do lots of times.

Having a gas heater on thermostat would be cool, but seems like that would cost way more out the gate. Plus I love standing around a good hot wood heater anyways.
This is my method. Have a lb white 150k btu jet heater to knock off the initial chill, then off. Fire the wood stove soon after. Maybe stoke it twice for an 8 hour shop session, (5 gallon stainless bucket of water on stove for humidity). 70 degrees in shop rest of day.paradisepwoffrd said:I hear that putting pipe in the floor is the ticket for new construction.
I love a woodstove but the downside for me is time. The stove in my last building would take 2 hrs before it was warm. I only fired it when i was going to be in there all day. Otherwise i used a small propane heater nearby to knock the cool off.
My new house had an existing block building. Have thought about wood or waste oil furnace, but not sure it's worth installing a chimney.
CHASMAN9 said:Absolutely, whatever you can afford at the time is the right way to go about it no matter where you are. I mentioned that if you are on slopes, definitely go with stepdown footings like you said and block to adjust for grade. I've seen such poor subgrades before that we had to cut the flat grade down 6-8' on the backside and drill Caissons to support the entire house structure and it was on a crawlspace. JD's pad looks pretty level and would be easy enough and cheaper to pour on grade for him if his subgrade is suitable enough.
