"Puddle" Concrete Construction
"Puddle" Concrete Construction
(OP)
Anyone know what "puddling" is in concrete construction. It was a term used in a webinar today in the context of high strength concrete columns. It seems to be a way of continuing the strength of the concrete column through a slab. Thanks in advance.





RE: "Puddle" Concrete Construction
Columns sometimes use higher strength concrete than the floor and there is concern over the section of concrete in the floor within the column "footprint".
ACI, for example, limits the difference between column and floor concrete strengths UNLESS you puddle the higher strength concrete into the floor over and around the column.
The lower strength concrete is then immediately placed in the floor around this puddled area with the two types of concrete mixed/vibrated together such that there is no cold joint formed.
Timing here is very important.

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.
