Pouring a concrete slab for a portable building myself?

I was hoping to save a little money by pouring a 10x12 slab myself. Does anyone have any insight or recommendations on things to do or not to do?
Thanks
Thanks

Make sure your pad is level and make sure your form is square. These seem like no brainers, but I see people mess this up all the time.

Nah. I'd pour it 4" thick and reinforce with wire. Form it up, dig you about an 10" deep footing around your forms, back the truck up, dump it in and screed it with a 2 by Foe.

If you have to ask, you probably shouldn't do it yourself.! Just saying.!

Stake the hell out of the outside of your form keeping the inside edge on a string line. A form "blow-out" while pouring is no fun.

You have to start somewhere. It's not exactly rocket science.

After pouring and smoothing, constantly go around tapping the form boards with a baby sledge hammer to get bubbles against the form boards to rise. This will help ensure smooth exposed sides of the slab.

A 4" slab of those dimensions is a yard and a half. You can rent a mixer on a trailer with an already mixed batch that has been retarded for you. Get a big truck if your gonna do that though...heavy. And see if you can rent one of those industrial vibrators and a bull float.
Oh yeah...and all that stuff that the other guys were saying about forms...do it.

Dayum....pretty obvious that quite a few folks on this board have poured a slab before. Don't find that too many places.

Go for it. Renting a mixer or a georgia buggy would be your best bet. You can get a truck to deliver a 1.5 yards though.
Let the milk rise to the top then screed with a 2x4, as was said before. Move it across the surface back and forth like a hacksaw. You may be able to pull that amount of wire mesh from jobsite scraps.

I poured more slabs between the ages of 15-18 than I want to for the rest of my life.

I only helped with 2 slabs and one REALLY long driveway when I was a teen. Was enough, though. Only done a couple as an adult, and only because the "professionals" want way too damn much money.

i have 3/4 of a roll of 6"x6" 6 gauge w.w.f. left over from a job i just finished. i'll give it to you for 1/2 price of a full roll.

I don't need it, but OP this is what you need for the slab.

Do it at night bc this heat might crack it if it gets too hot.
Make sure you have a set retarder with this heat right now as well.
Try to make sure it doesn't slump too much (less than 6" is good). If its too thin of a mix it will probably crack later on. Having a lesser slump will make it more difficult to work with but strength will be much better.
