- Abstract
- This report presents data on the fire resistance of concretes having oven-dry unit weights in the range of 30 to 100 pcf. Relationships between slab thickness and fire endurance, based on 250 F rise of the unexposed surface, are given for concretes with various unit weights. Data are also presented on temperature rise of the unexposed surface and temperature distribution through the slabs during fire tests. Design charts for estimating the fire endurance of two-course floors and roofs are discussed, and relationships between mositure content and relative humidity of fire test specimens are presented.
