What type of concrete would be best for a shed floor?

Bagged you mean? How big is the shed? I've just finished a shed floor, the shed is only 2.5 X 3m but it was worth getting 2 cubes of builders mix and mixing it myself. Did it in 4 pours, couldn't be bothered doing it in one lot.

Depends what the shed is to be used for - does the floor need chemical resistance, weight of items that are going on the floor. How much you wish to spend - coloured concrete, polished etc?

Its around 3 X 3m, I will be using it as a hobby workshop so nothing fancy, trying to do it as cheap as possible without it affecting quality etc.

Use plenty of reinforcing mesh. Lay it a little deeper on wheel tracks & entrance way.

as long as your hobby doesn't involve cummins engines and gearboxes type sizes and weights, set up to lay a slab 75mm deep, 3x3 is 9sq by75mm is only .675 cube, allow say 0.8 of a cube, get a truck in, ask for 27mpa or 30 mpa, will cost less than $150, which if you work out 7 bags cement ($95 min)( 27mpa) 0.8 cube builders mix - another $50, hire or steal a concrete mixer, likewise a wheelbarrow, completely stuff your back and still end up with uneven mixing when it comes out of the truck you have up to 2 hrs to slow down and get it right, the whole lot is then done, and you know it will not fall to bits in 3 yrs

Yarrrh! I just love it when someone asks for the best type of something and then it turns out what they actually want is the cheapest job possible.

Thanks for you answers! and Yarrh Daryl14, maybe I should have rephrased it "best WAY to do it on the cheap"

Don't forget to put polythene under the concrete

Bejassus Skin,you could land a Jumbo Jet on 30mpa. Standard concrete is 17.5mpa and all you need.

yeah, but for the minimal extra cost, on a laymans 75mm slab ( anywhere from 100 to 60mm )it WILL handle cummins engines and gearboxes, even when you drop them ( go on, ask me how I know this, lol
a 75mm slab of 17mpa will not like a wood lathe table being bolted to it, I've also repaired patches where a car jack has punched through such, especially when the 'on the cheap' job usually means the best average will be 60mm

not so much the concrete but what is under it . aim for 300mm of well compacted hardfill, compact in 150mm layers with a 80kg plate compacttor , 100mm 20 mpa slab , a bit of a thickening around the outside and throw in a bit of mesh or some d12 @ 300 each way . dont muck around mixing premix . get a truck
