Filling an Existing Floor Pit
Filling an Existing Floor Pit
(OP)
I need to write a specification for filling an existing floor pit with concrete. The pit dimensions are approximately 22' x 18' x 5.5 feet deep. A concern was raised that using a normal weight concrete would result in unacceptable shrinkage around the perimeter of the pit walls, and that I should consider going to a "low shrink" concrete. I am not familiar with that type of mix design. Can anyone provide an insight into "low shrink concrete" and or any potential problems with filling the pit with normal weight concrete.

The pit partially surrounds two turbine generator foundations. The turbines have been removed and one of the existing inertia blocks is being incorporated into the foundation of a new HRSG. The HRSG has been located in an unfortunate spot where it will partially overlay the pit on one side, pass over the pit wall, and overlay an existing concrete slab on grade on the other side.
