How Thick Should a Concrete Slab be? - The Constructor

For this criterion the fire rating of a floor is the number of hours necessary for the temperature of the unexposed surface to rise by a given amount, generally 121.1C (250 F). For a 121.1C (250°F) temperature rise, a 76.2 mm (3-1/2 inch) thick slab gives a 1-hour fire rating, a 127mm (5-in) slab offers a 2-hour fire rating, and a 152.4mm (6-1/4 inch) slab provides a 3-hour fire rating.
