Column concrete placement
Column concrete placement
(OP)
Is it ok to place column concrete by pumping it into the top of the column form? Is there any concern about segregation? The column clear height is about 9 feet.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Column concrete placement
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

RE: Column concrete placement
The main concern I've seen with regards to segregation isn't necessarily with free fall, but with horizontal transportation as the last sentence in JAE's second screenshot states. The intent of ACI 301 in my eye isn't for you to pour columns and walls in lifts or stick your conveying equipment down into the forms. It's more to not deposit all concrete for a long length of wall or slab in one spot tens of feet away and then move it into place from there.
