Can anyone give me good tips & advice when I'm going to cast my own stones?
What materials are the best choice?
Mixing etc.?
Can you color the cement/concrete in any way?
I am grateful for all the tips I can get.
 
What will you use them for? How big should they be?
 
Hello Crebel!
I am going to use the stone to build a wall without mortar.
That is, the stones should lie on top of each other without being mortared with cement.
I was thinking of a size of 250x250x400 mm.
 
Oh, then you need a lot, I guess:-)!
Concrete is good and fun to work with in moderate doses. It is possible to dye it with pigments, but I have never done it myself. I read somewhere that someone found concrete dye pigment at K-rauta. Otherwise, I would ask in a paint shop.

Can't you find concrete stones to buy that you like? I find it hard to believe it will be much cheaper to make it yourself if you buy bags of ready-mixed concrete instead of mixing cement and sand yourself, and it's quite a lot of work if you're going to have it for a whole wall.
Concrete is quite unyielding, I've noticed. It always takes more than you expect.
Have you worked with concrete before? If not, I can give you some more information...

It would be 25 liters/stone or 2 bags of ready-mixed casting. Isn't it better to buy ready-made stones? Våxtorps Betong has a slotsmur 200*140*400mm in several different colors at about 36:-/each.
 
You can find Pigment at capton.se or grace something
they specialize in pigmented concrete,
there you'll also find different treatment options.

question? isn't it possible to cast the entire wall in one piece with the pigmented concrete, where in the mold you make the finished casting's outside look like block stones.
(what a solution, should be patented, hahaha)
Maybe it can save some time instead of casting stone by stone, if I've understood it correctly.
