Concrete, weight/cubic metres?

The message k
from "ARWadsworth" contains these words:
Possibly a stupid question, but how many 25kg bags of ballast (with a 5:1
mix) would it take to make 1 cubic metre of concrete?
I really have no idea how to work this out myself.
A lot. You really need to think about buying in bulk.
Figures I have are for a cubic yard but I am sure you will be able to
work out the fiddle factor without any help from me. Tons and Tonnes are
almost interchangeable.
@ 5:1 1.446 tons all-in mix and 0.231 tons of cement.
If you want to go down the equivalent 1:2:4 route that would require
0.513 tons of sand and 0.933 tons of gravel for the same amount of
cement.

Thank you Roger.
I will not be mixing a cubic metre in one go! I now have an idea how much
ballast is needed for the smaller jobs I need to do. It will be bulk buying
as it is much cheaper (30% cheaper)
Cheers
