Now that's cheating (as I say sitting in my office with a thermostat set on 74). How much lime do you have to put in the concrete to get it to cure at -7?
-4 this morning on the way to work, but they say it should "warm up" today and tomorrow to 19 or 20, but then the bottom drops out until at least the weekend. Looks like we may be above freezing in a week... maybe.
No lime. We put 100 LBS. of calcium chloride in a 10 yard load of concrete, that will help keep it from freezing as we pour.
When we do walls, we will tent and heat for about 16 hrs., open the tent to pour and close it back up as we finish. Then let the walls sit for 1-2 days before stripping them.
Like I said it was 80 degrees under the tent today, the tent is the last thing to come down when it is as cold as it has been.
When we do slabs / floors those are usually heated for at least 2 weeks before we pour, and then they remain heated until the contractor decides to turn them off. When we do slabs, it isn't the heat that bothers us, its the carbon monoxide from the heaters burning dirty and the power trowels running constantly. But, we have a job to do and literally suck it up and get it down.
Right now it is a balmy 23 F with a light breeze at 30mph giving us a real feel of a lovely 5. There is just enough snow falling to remind you of a HALLMARK Christmas card
Started snowing in Lake Placid NY @ 10 am, and still snowing. Had to use 4 wheel drive to go 15 miles. Haven’t heard anything about what we got back home, still in NY. I think my drive home will be about 3 hrs., once I leave here.
15 now, we are suppose to break above freezing today. I read that if you combine all the US temps for Jan 5 it was the coldest night ever in US record keeping history.
We are supposed to go over freezing today too (34). First time since before Christmas. Unfortunately, we are supposed to have freezing rain most of the day. Shouldn’t last long. The next few days are supposed to be nice. 40s and even 50s.
