It seems that the most impossible thing to find on the web is definitive info on fire resistance ratings of different concrete blocks (thicknesses, materials, grout effects, finish effects, etc.) Can someone help us out at this Missouri Architectural office? We need 2 & 3 hour ratings of our steel building framework, some of which is encased in concrete block. Any help is much appreciated.
