The access makes ready mix problematic.
As it is, im planning on buying the aggregate in 25kg sacks, so as i can carry it, by hand, through our kitchen....
When i last got a quote on ready mix, it was £70 per cube, with a £70 delivery charge. So about the same cost as doing it by hand, i think.
That quote is not recent though - again, its just easier with this one to mix by hand (with a mixer...)

Anyway, my next question -
This has been discussed before - how to tamp concrete when it is enclosed by walls. Someone suggested fixing batton to the wall above the surface and using a hanging tamper, but the walls are also not parallel which makes it more awkward.
What about shuttering off 8 inches or so along the walls, and casting a level edge that way. Trowel the top smooth, remove the shutter when its gone off, and then tamp off that surface? The join would be weaker though.
I have the corner in the photo, the corner to the right of that one, and then the last side will probably be accessible.
So that was 52kg per load (before water), right?
That would take me back to 2x 25kg bags, and a half bag of cement (62kg) for a 4:1
Do you reckon that is more like it? My numbers before were just off the data sheets, rather than real life.
The specs (i think) say that the 150 is a 90ltr mix (max load, not drum size)
That's (obviously) 0.9 cube per mix (max)
90L is 0.09m3
900L would be 0.9m3
