Base for garden shed

[ss]

I will be shortly rebuilding my garden shed, I have about a ton of those red drive chips, would it be ok to mix this with cement and use as a base?

Not quite sure what you mean, but don't see why not. Good strong concrete includes a range of sizes of "filler" from "stones" down to "sand". For a garden shed it probably doesn't matter much.

Its those sort of `chips` about 2 to 3 cm in `diameter` that are used for driveways.

If theyre not porous, sure. If they are, no.

In the same way that you don't make hills out of chalk, only sandstone?

You next a mix of fining ... so a s long as you are also using sharp sand you should be OK

1:3:5 would be good enough for a base ... lay at least 100m thick to avoid cracking. As chipping are small, if you mix it with wet slump, it will level easily.
