In this video I'm sharing with you some things about cold weather concrete mixes that you probably don't know, but you should. Winter concrete mixes are different than summer concrete mixes. Two major differences, at least in Maine, concrete companies use hot water in the mix and most people add accelerators to the mix. Knowing how the concrete sets-up when both of these are added is critical to getting a good job. The video explains some other things to watch out for as well.

These kinds of videos are so helpful. You dont owe us a thing, Mike. I wouldnt share my knowledge with somone that I wasnt making money off of.
Mike, once again very informative you are a wealth of information. You should really think about writing a book so in case your videos crash,something on paper and photos just something to think about!!!!!!!!!!!!!!!!! like they say on Lake Winnipesaukee!!!!!!!!!!!!!!! if you’re out sailing,,,,,,,,,,,,,, and the wind stops!!!!!!!!!!!!!!!!!!!!!!!!!!!! you better know how to ROW !!!!!!!!!!!!!!!!!!!!. Heard that a long time ago. Take care yourself. Be safe, Samuel bacon.
Very nice job
I work for a commercial floor companies summertime they'll put one or two percent in the last third of the project
New Year's at Magistrate on slopes you just have to have a good guy operating it and good rake men
Thanks Mike always learn alot from your videos
Hey Mike. We are in Maine too. I’d like your thoughts on those heat blankets you have on the ground there. We do the ground work also, lay these out for frost protection before and after the pour. We double them up also, when real cold we add a foot or more of hay then tarps on top. I’m getting sick of the hay haha, can I do away with it? Thanks
Hey Mike, what about using some intermediate guide bars for screeding a large slab which can be removed as the pour progresses? I have a 28 x 32 slab that I want to pour. I thought if I can speed up and control the screed it would be a great help. I’ll probably have to pour in lower temps but not freezing. Not much help just me, and at most a couple of others. I have done a single garage before.
A slab that size I would expect to have expansion joints in place, these can be used for screeding off or stop ends put in where you would pour a panel and miss every alternate panel then when the poured panels have cured sufficiently to walk on ie the next day you pour the intermediary panels which gives you more control over the finished levels and quality of workmanship. Cold weather : Above freezing and rising .
As a guy who has poured a lot of concrete alone or with inexperienced help, I agree with @johnaustin's advice. I wouldn't do it exactly like he says, and you need to find your own way to divide it into two pours. In my area, the concrete plant charges a "short load" fee for less than 5 yards. 28x32 breaks down into a couple of separate pours without incurring extra charges.
Another option is to set up a form similar to what Mike had in the garage portion, even though you don't have a step down. Be sure and put that form where you would want a contraction joint. I don't recommend an ecpansion joint unless the slab will be out in the sun, causing significant expansion. Order your second truck with an hour separation, so you will have time to float the first truck before starting the second truck. Then, pull the form out minutes before placing the second truck. Do not pull the form up. Pull it sideways.
Good luck! Consider using no accelerant and bring plenty of lights. There is no substitution for the experience Mike's crew has for getting it down fast, so give yourself some time.
How about that galvanized the expansion joint that you stick in the ground we call it Johns Creek leave it right in your joint and you can caulk it

very good informations! i have a project and it's good that now i know that👍
Hello Mike how come you don't use your magic screen to pull your wet screens
Just wondering if they batch the concrete there like they do where I pour. You order hot water and they batch it with hot water and you get hot water on the truck but they pull out there and wash down in cold water which kills the hot water they batch with.
Oh oh, that imported concrete mix will be tatariffs. $$$
