[TheForge] Fw: setting fence posts

[David E. Smucker]

Dan, I don't agree, not throwing stones here just concrete.  For the highest 
strength concrete you want a very "dry" mix, problem is that this isn't easy 
to place.  There is a lot of data out there on this -- not just my word. 
But from my experience the worst foundation I every had to remove was one 
that was placed in about 1920 using what they called dry pack at the time. 
They made a very very dry mix and placed it by impact hammering it into the 
forms.  It was hell to remove, and didn't even have rebar in it.   We were 
inside a mill building and didn't really want to blast.

In the case of the posts by using the mix completely dry you get a slow 
hydration of the cement -- from the moisture in the ground, makes a very 
strong concrete -- it just that it takes some time.

No question if you a going to do lots of these the a commercial mix and 
pumper is the way to go.

Dave
