calsi-crete ??
we are looking at utilizing an existing roof for a potential extension of space.  the existing roof is composed of steel bar joists spaced at about 6'-8" [2030 mm).  the roof surface is supposedly made up of a product called "calsi-crete" precast planks.  
we suspect that they might be some kind of gypsum/concrete product but have no other info on them.  strength, stiffness, reinforcing, suitability to work as a floor.
anyone out there know anything about these?  would appreciate any information you might have.
check out our whitepaper library.
do the "calsi-crete" precast planks span between the joist or are there other framing   
no bulb tees indicated....panels appear to span from joist to joist and are 5" thick.
after doing a little web sleuthing, it seems that calsi-crete was a subsidiary of continental materials corporation of chicago.  calsi-crete produced precast lightweight concrete cellular slab panels.  you might try to contact continental to see if they can help.
thanks, taro - will check it out.
