Picture of Concrete Paver Floor
I wanted a concrete floor in my shed but the shed was at the back of our property and up a hill
  No way to get a concrete mixer back there
  I didn't want to push a wheelbarrow back and forth
  I didn't want to pay for a concrete truck and cement pump
  And I wanted to do it an hour or so at a time, if it took a year it didn't matter
  And I had to use the shed during that time...
So I decided to pour cement pavers and stock pile them until I had enough for the whole floor and could lay them.
You'll notice from some of the following photos that my shed is a little unusual

Step 1: Build a Form

Picture of Build a Form
 The first step is to build the form for the pavers. My design for this was based on the amount of concrete an 80 pound bag of premix would make. It ended up being 22" square and the concrete came up to ~1 inch below the top of a 2x4.
 For my shed I needed nearly 30 pavers of this size. For the first 10 or so I made a form that held a single paver but when that form needed to be replaced I built one that held three. Both of these forms had issues, I would build forms of two next time. The single was slow and the triple was VERY heavy to turn over and the middle paver was hard to get out.
 I also found a float handle and screwed a bit of plywood to it for flattening off the pavers... any bit of wood would work just as well.

Step 2: Pouring Pavers

 I used a wheelbarrow to mix in and made an effort to keep the mixture as dry as possible. After pouring it into the form (while the concrete was still wet) I hammered on the sides of the form until I got bored to get the bubbles out.
 Hopefully all that will help the cement last longer but I didn't notice any outward variation.

So glad I stumbled upon this 'ible. Actually planning on doing our own pavers also. My questionis, Did you put anything in to line the forms to aid in realse of pavers? Thanks

I did, once or twice but found that it didn't make much difference. I put a little latex calk in the corners so the concrete couldn't lock into the cracks and I found that the weight of the pavers allowed them to fall out quite easy (sometimes with a little persuasion (hammering on the back off the form))
Good Luck

I know this is an old project but I've been considering doing my own concrete pavers like you did. I have some questions.

did you let the pavers cure in the forms? how long?

how did you get them out of the forms? did you take the form apart or did you just turn the form over and "dump" them?

How has the floor held up?

Yes, I dumped them out. Because they were heavy (80 pounds each) I wanted them fairly hard before I did it (maybe two-three days). I rushed a couple of times and they broke.
After I made them they sat for a month or so, I think that helped them cure and none broke when I placed them on the sand bed in my shed.
They've held up really well. The real test is under my wood lathe (it's a few hundred pounds and it can jump around a bit when I have something unbalanced on it). No cracks so far.

Can you imagine concrete jigsaw pieces? At the moment that's the only thing I can think of that would have made this better.

Wow! Could that be done? That would be so utterly amazing!

You could make the forms out of thinner wood or even plastic (probably better).  You would have to do a minimum of four at a time in a 2x2 configuration with the pieces interlocked.  It would take some doing, but it could be done. 

Awesome idea pouring your own bricks.  Better than trying to purchase them a two to three bucks a piece.
