Precast Hollow Core finish
Precast Hollow Core finish
(OP)
I went out the a job site and noticed that the concrete on the bottom side of the hollow core plank appeared to look like it was "stretched" or "ripped." I've attached a photograph of one area. Would you consider this finish "typical." It's the first time that I've seen it.
Thank you
Thank you

Some systems do not use zero slump concrete, but produce a very smooth finish, but the beds are much shorter and are more acceptable for a smooth architectural bottom surface.
Fortunately, most (85% are PCI members) and the manufactures keep good records and logs of all production and have very acceptable testing procedures and quality control procedures for years.

As a design engineer the reasons are just excuses, but the appearance it a clue/hint to a possible quality or reliability problem.
