Want to mix up some no fines concrete ... anybody know correct mix, I have done a bit of Googling around and found
6:1 8:1 and 10:1
I have put in a struts to support shuttering, these are fixed to an 'on edge' timber. (As per drawings on this site)
I had to cut a slit trench for the timbers (struts run at 60 degree to top waler of shuttering)
I want to back-fill behind the timber to provide full support when concrete raft is poured.
I can leave the concrete in place afterwards as it is well below ground level.
