We are trying to determine fire ratings for an existing concrete elevated floor (pan joists at 2'-1" on center with a 2.5 inch slab). The code seperates the concrete categories into cabronate base and siliceous base. Is a core sample and testing the only way to dermine which type of aggregate was used?
Thanks in advance.
