[Subject Prev][Subject Next][Thread Prev][Thread Next]
By definition, lean concrete differs from regular concrete by only having less
cement.  I would not use sand cement for any application including this one.
Again, assuming that the steel section is adequate for all soil pressures, I
would use a 1 to 1.5 sack mix.
