fire resistance ratings of concrete masonry.

FIRE RESISTANCE RATINGS OF CONCRETE MASONRY ASSEMBLIES

Concrete masonry is widely specified for fire walls and fire barriers because concrete masonry is noncombustible, provides durable fire resistance, and is economical to construct. Chapter 7 of the International Building Code (IBC) (refs. 2, 3) governs materials and assemblies used for structural fire resistance and fire-rated separation of adjacent spaces.
