Abstract
A mason contractor built a multistory wall bearing building with 8 in. (203 mm) hollow block that had a two-hour fire rating using the equivalent thickness method. The majority of the walls were built with #5 rebars at 48 in. (1219 mm) on center. There were bond beams at the mid-height and the top of the wall. The specifications required that the wall assembly provide a three-hour fire rating. The local building authority would not accept any empirical calculations and demanded full-scale laboratory fire tests. This paper discusses the various procedures that were used by the fire research center to test the block, what materials were added to the 8 in. (203 mm) block to increase the fire-rating, and the actual test results. This test program demonstrated the efficiency of using spray-on rock wool fiber material to increase the fire rating of existing masonry walls.
