Concrete Masonry Fire Resistance

2017-7-5  Concrete masonry is a noncombustible construction material possessing excellent fire-resistive properties. The resistance of concrete masonry to fire is well established by extensive testing to be a function of the type of aggregate used in the manufacture of the masonry units and their equivalent thickness. The rated fire-resistive periods for block walls can be determined by knowing this
