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 little appreciated property of the Google search engine is it's ability to
answer 'plain language' queries: I typed the search string "How many 25Kg
bags of ballast to make I cubic metre?" and in 0.69 seconds it responded by
pointing to a Community Forum discussion about shed bases.
