As per subject, what size is a 'bag' these days and the rough cost of a
'bag'?
Supplier worked out the job would need approximately 7 'bags' and
delivered 7. I've just looked and they are what I would call 'half bags'
25Kg at around £3-80 per bag rather than the equivalent of 1cwt or 50Kg.
25kg is the standard bag these days...
Is 7 half bags enough for the 2 cubic metres of concrete I specified?
Depends on how strong you want it... For a medium strength mix like C20
you would need something like 700kg of cement and 3600kg of ballast.
