I probably have a similar Jula mixer at home and remember that more than 4 bags and 4 shovels of gravel shouldn't be discussed. Also, you have to be able to tip that thing with good results.
(I filled a wall with concrete and reinforcement to act as a retaining wall with earth pressure)
6 sqm with a 10 cm slab easily becomes 600 liters.
Now I think 100 liters in that mixer is too much - One bag is about 12 liters which means 50 bags of concrete, so expect at least ~15 runs in the mixer.
With 12 liters per bag, it would take 8 if it handles 100 liters, and I think that’s impossible.
8 bags at 25kg each would be 200 kilos of concrete + water. Tipping that would probably be exciting...
(Also, I don't think it mixes well in an upright position; it works best at a certain tilt, meaning less volume in the mixer)

Thanks to you all,
I will eventually dig out the entire basement and thought to start with the small room, which is 6 sqm, to see how it works. Therefore, I bought a concrete mixer with a 2-year warranty, so if anything happens to it, I would get a new one instead.
I checked with Skanska on how much a concrete truck would cost, and I was told I would have to rent a concrete pump, which would cost quite a bit. Additionally, we have a lot of furniture and stuff in the basement, so in that way, a concrete mixer is a good alternative.
Kind regards

My concrete mixer can only handle half a sack of cement at a time, which is a bit. Otherwise, it doesn't mix well. I probably wouldn't take on a bigger job like pouring a floor with my own mixer unless absolutely necessary. A concrete truck saves a lot of work and probably gives a more even and better result.
OK, 6 sqm is not a big job, so it's probably not worth it to get a truck.

Now I would like to have some experience with casting technique, I have done it before three times (6, 2, and the last was 10 sqm) but didn't get any good finish on the concrete. I checked a bit and saw this tool. http://www.blocket.se/dalarna/Betongsloda__sloda__handsloda_25967809.htm
How did you achieve the best possible result? No carpet or tiles will be on the concrete, it will be parquet flooring afterwards. Best regards.

Really want to avoid self-leveling compound to save time and money, instead spend more time during the casting occasion but how do you get an okay (not perfect) but acceptably even concrete slab? That's what is interesting to know.Stefan N said:

600 liters with a tombola is not difficult but not so fun either....
.......make sure to have at least 2 people so that you always have someone mixing....
Good luck and don't forget to take pictures all the time....

You "stålar" by hand....surely someone here can explain
Just poured a fine batch on a part of my garage floor that's going to become a storage room. I used a Jula mixer, and it took three bags of fine concrete in the mixer per batch; more doesn't fit if you want a good mix. I used 30 bags over about 9 square meters. It took two hours, not counting the time to lay the leveling guides. So pouring on smaller areas is not really a problem (I've done it several times before). I think anyone can do it unless they're really clumsy. It's important to have good leveling guides with plenty of support underneath and to go over the surface several times until nothing is left in front of the screed. Then a larger trowel to correct edges, keep a reasonable amount in front of the screed so it's not too hard to work with, and a bit of general touching up/smoothing. To speed up the pouring, I filled the mixer with three bags, started the mixer. Added enough water for a good mix, let the mixer run while I took the wheelbarrow with the concrete I just poured, moved it to the pour site, spread it, and leveled it as far as it would go. Back to the mixer, adjust the water amount for the batch going in the mixer, let it mix in any new water. Pour into the wheelbarrow. Add three new bags, add enough water, take the wheelbarrow, etc. This way, it keeps moving along with no waiting times at all, and the pouring is done faster than you’d think. It helps if there are two people, but I did it myself.
Hello REMS and thank you for a very good response.
My tombola is 165, how big is yours? In my case, I am going to cast a 10cm thick slab, which means a lot of bags, a pallet and a little extra help will be needed; otherwise, it might get a bit challenging, I think.

Measured a bit and it seems to be the 130-liter variant I used. Maybe you can fit in 4 sacks then? It's easy to be tempted to add too much water to get a more workable mix, but that will result in a poor mix. You should use as little water as possible within reasonable limits. You must still be able to handle the mix and be able to spread it with the board. One sack of Finja's concrete Fine/Coarse yields 13 liters of finished concrete and should be mixed with about 3 liters of water.
A 10 cm slab seems unnecessarily thick. I helped pour the floor in a machine hall and there the floor was 8 cm thick. And they drive in machines weighing tens of tons. So a slab of 6-8 cm should be sufficient without any problems. So 6 cm thickness gives 60 liters per sqm and 360 liters in total. That is, with 13 liters per bag, around 30 bags with a little margin.
