WebIn other words, if the structural design dictates the use of a 12-in. (305-mm) thick wall, it is often easier and more cost effective to use a single 12-in. (305-mm) wythe rather than a composite system consisting of 4-in. and 8-in. (102- and 203-mm) units. WebOct 1, 1995 · The fire-resistance rating of concrete masonry walls depends on the type of aggregate used in the units. A 2-hour rating can be achieved by a wall with an equivalent thickness of as little as 3 1/5 inches when expanded slag or pumice is used or 4 1/2 inches when siliceous gravel is used as the aggregate. For cored units, the equivalent wall ...
