I need to cast some piers (70 liters total) this week and now it's cold. Therefore, I need frost protection or move 6sqm of the plot into the garage... Ready-made piers are not an option.
Which frost protection agent is recommended?
Once mixed according to the specification, is it just to pour as usual and look happy?
Some frost protections seem to be aggressive on galvanized and reinforcement. Are there frost protections that are NOT aggressive? Maybe I can ignore this, as the post shoes are sufficiently durable?
Damn winter!
How do you guys in Norrland handle this, you should have an eagle's eye on this.....!

We cast footings in subzero temperatures. What we did was build a small house out of styrofoam and put in a car heater that was running hot. Though it might be a bit cumbersome if there is a lot to be cast. 
It is also possible to mix with hot water to speed up the burning process.
If it's not possible to mix something and then proceed as usual, it seems I might have to do the extra work that comes with ready-made plinths. Among other things, I have an old foundation right where a plinth needs to be placed, and this foundation must be demolished.... Building heat tents or using Styrofoam molds isn't appealing though......
more cement in the concrete makes it cure faster and at a higher temperature. Concrete is sensitive from +5°C at the concrete plant, they mix in water that is 28°C in the winter, which is called warm concrete.
If you don't want to do any extra work with insulation or more, you can forget about pouring in sub-zero temperatures.
Sure, there are additives that make the concrete cure better, etc., but the measures before and after pouring cannot be avoided.

I’m beginning to understand that this is how it works. I think the recipe will be a set of 60-kilo plintar from byggmax + a trip to the gravel pit to max out the trailer with some sand. It’s just a 2.5 sqm landing to the entrance we’re talking about anyway.
Old thread but I have the same concerns about how urgent it is to complete the casting.
The solution has come from maxit.

Continuing on this old thread and hoping it gets bumped up.
I'm going to cast a small edge so that there's not a 90-degree angle into the garage (single garage) which is about 7 cm higher than the asphalt outside.
Do you need frost protection at zero degrees or a few degrees below zero since it's such a small amount to be cast?
