   Call around the various suppliers in your area and find out if anyone has winter mixes. They normally come in 4 different levels of protection. Right now I'm using level 1 for the footings and will be switching to level 3 and 4 for the walls. This allows me to pour in sub zero weather without heating the columns.

   These additives add about 15 bucks to the cost of a yard but when you consider that you don't have to tarp or heat, it's worth the money.

   We pour easily at minus 10 celsius which is about 14 F. without any protection.

   With a wind chill of -47 F this morning, I don't care if they make level 30 cold weather mix, I ain't going to be out there pouring nothing!

   Had to shut the jobsite down this morning because it required only 30 seconds of exposure to freeze skin.

   Let me know how you make out,

   About 4 years back there was a crew outside my building pouring concrete and putting up a block wall with fairly steady -10F temps and, on several occasions -50 windchills. They just tented the site well and kept on working. Had to give up on the on-site mortar plant, though, and have the mortar trucked in.

   I could have spent a lot of money for a few days to do that but the weather is supposed to go up to above freezing on Thursday so it's not worth it.

   Had a meeting with my foremen this morning and unanimously decided that it was safer and better for the men to try again tomorrow. A successful site in the making.

   At this time of year we ask for 2% calcium addition, and the batch plant uses hot water for all orders. We have insulated tarps 12'x24' that are laid on top of the finished concrete. The heat of hydration will keep the slabs warm for the first 24 hours, and after that you can tent the tarps a little and use heaters. Although curing will be faster if heated - which means you can work on the new concrete surfaces sooner - the main thing is to protect from freezing for 48 hours. Leave forms on for a few days if possible, mostly to protect the still-green concrete from damage.

   Minus 25 Celcius today and it didn't stop us at all. We used only a level 2 mix because the forms are in a trench, out of the wind, and we will cover with just a plastic tarp, no heating. Tomorrow the footings will be stripped and backfilled immediately for protection.
