there are building codes/permits.....CAN you even do it ..is the real question....check with city...how you build it will determin price
64 sq' is nothing......plus it's an existing slab in need of repair. No permit required.
~108 sq' and above needs a permit for a structure.
I did mine with a pick a mix outfit over 20 years ago and it's still good as new. About 10 X 12. I'm not a concrete worker but watched a bunch of sidewalks being poured and asked stuff about when to finish it etc. It's all about how much water and when it comes up and when it goes down. Too much water = Bad
My first question is "What kind of finish do you want?"
I went for broomed as it's kind of a no brainer. If you want smooth (Steel trowel) you need to be a lot more skilled than me. I could have saved $$ by mixing my own but I would have either broken my back or coughed up the difference in beer money by enlisting friends. The mix would not have been as consistant either.
You are looking at less than a yard / meter whatever they sell it in now so likely a minimum call out. Or 40-50 bags of premix and renting a mixer (Inconsistant).
40 years ago I hand mixed and placed a 350 SF slab in sections over about a week. Did wonders for my waistline.
Hit youtube to see if they have anything. (Or stock up on beer)

General concept but IMO a way too much water. Look for a better example.

Concrete companies have a minimum charge usally 3 cubic meters...
10ft x10ft x 4 in pad = 1 cubic meter
32 c2 is the concrete required(weaker concrete will flake and crumble), $150- $180 per meter ( 3 meter min)
Is there anything else you can pour in concrete to make it worth while???
Patio stone will shift and crack, depending weight on them..
Bag mix for a pad is NOT recommended unless you rent a mixer. Be sure to purchase extra bags of Portland to add to bag contents..
Any questions let me know.

Perfect - that is exactly what I wanted to know. Thanks Paul.
Is there a pick-a-mix in the area? They mix what is needed on site. Likely more per yard but you don't pay for three when you only need one.
A small rental mixer might only do one bag of pre-mix. If you need 40 bags it's a long pour with the first pour setting as you mix the next.
If you go with conventional ready mix you could get a massive truck even though you only need a small load. They may need a clean out area to dump excess concrete and clean the chutes.
got any friends in construction? If so they could talk to the concrete guys and maybe they could swing by your place on the way back to the yard. They gotta dump their left over load and if you have it formed up and ready to pour you could likely get what you need for a case of beer or more. You'll have to do all the finish work yourself but...
An old buddy of mine formed in a new front step and was all ready for the truck to swing by to pour it. he wasn't home when the truck got there, so the driver just poured it. Well the form job was subpar and the top step blew out. Driver did the best he could to shore it up with what he had but when it set there was still a huge bow in the top step, and it really looked like ***. Make sure your forms are very good and stout.
I need to pour a slab in an existing pole barn here, but it's too big to fall under the left over load category. I'll be hiring it out though as concrete work is not my idea of a good time.

^^ Landlord of my buddy just had a truck come and dump it right onto the lawn and then the landlord and his buddy flattened it out. It's pretty cheap looking (it's not very flat) but gets the job done for something just to park a car on. Seems like concrete mixed with rocks to me (which adds to the cheap look but seems pretty sturdy). No idea what it cost but supposedly was very cheap.
LOL
Concrete is always mixed with rocks. It's called aggregate and that's what gives the concrete strength. Main components of concrete being aggregate, cement, water. You can use additives and stuff to get specific properties out of the concrete but I wouldn't for a slab to put a shed on or whatever.
We poured a small pad, just contacted the concrete company and they called us when they had a truck with left overs in it. We had to be ready in an hour. It was all framed and ready to go so an hour lead time was no problem. We knew it would be this day or that day kind of thing
