Parallel cracking of a suspended composite slab
Parallel cracking of a suspended composite slab
(OP)
The contractor has made me aware of cracking to a recently poured suspended composite slab. The slab is 5.5" total thickness over 3" composite deck, supported on load bearing walls at 10'-0" o.c.. Deck sheets span, minimum 2 spans. The hairline cracks are 2'-0" o.c. approximately, parallel to the deck flutes, perpendicular to the load bearing walls and parallel in nature. The subcontractor was contractually forbidden from using ride-on power floats to finish the slab, but did use such equipment. Has anyone encountered such cracking, was it caused by the ride-on power floating equipment and is the structural integrity of the suspended composite slab compromised.
