metalfree concrete slabs
any suggestions for designing a metal-free concrete slab/foundation for an mri support slab?
i'm sure we could just design the concrete section, but it would be good if we could try to have some resistance to cracking.  
check out our whitepaper library.
use some fibre reinforced plastic (google it).
from what i read, durability is not known or thought to be less than desirable on the frp.

i don't know where your sources are from, but the transportation market is using frp reinforcing in limited applications and in state or provinces where de-icing is typical.  
that said, when you look at aci 440 for the necessary strength formulas, you'll also see a environmental factor that is applied based on exterior, interior and or exterior aggressive environment.  these factors are presently used to ensure the bars/slab will not fail due to degradation any more than uncoated steel reinforcing would in a corrosive environment.
