Fire rating of 4-inch thick concrete wall
Fire rating of 4-inch thick concrete wall
(OP)
I have a pre-cast concrete building that will have four-inch wall thickness. If I recall correctly, this should give at least 2 hours of fire rating. Am I correct?

A 4" thick carbonate agregate concrete wall will give you 1 1/2 hour fire rating. If you use light weight concrete you can get a 2 1/2 hour rating.
(Using carbonate aggregate concrete wall you'd need a 5" thick panel to meet a 2hr fire rating.)
I hope this helps. If you want a copy of the charts your local precaster might be able to fax a copy of it over to you.

I found the same table. Thanks for your help.
