Hollowcore Plank Arrived Cracked
Hollowcore Plank Arrived Cracked
(OP)
48" wide, 8" hollowcore planks arrived at jobsite this morning with approximately 1/3 of them have at least one crack in the top surface aligned with the cores. Contractor said it is typical, but I've never seen or heard of it happening before. I can't seem to find any guidance on how to handle it. It seems to me that the strength of the plank hasn't been compromised, and it is to receive a topping. Should this be rejected? (obviously will seriously affect the schedule of the project and winter is coming)

I don't initially see a problem as long as the cracks are parallel with the span.

And if you do use them, make sure they have continuous support over the full width as they obviously have no transverse load distribution capacity!

For modulation purposes you have slabs cut longitudinally at various widths as to be able to cover the whole floor area with slabs, without compromising the strength of the floor.
However, one thing to watch out for, is that depending on how the cracked slabs are manipulated into position at the site they could break longitudinally when manipulating them dropping unexpectedly.
In any case I would sugest contacting the precaster to clear any doubts you might have.
