NCMA TEK. National Concrete Masonry Association an information series from the national authority on concrete masonry technology CONCRETE MASONRY WALL WEIGHTS TEK 14-13B . Structural (2008). Keywords: heat capacity, single wythe walls, sound trans- Heat Capacity (HC) Values for Concrete Masonry Walls mission classification, structural properties, unit density, (ref. 3), for further information). wall weight - Gravity loads (wall dead loads) on structural members such as lintels and foundations. - Dead loads to resist uplift and overturning for high wind INTRODUCTION resistance. Additional wall properties are also impacted by wall Concrete masonry walls provide a range of benefits, in- weight, although estimates of these properties are based on cluding structural integrity, fire and sound resistance, energy concrete density or aggregate type, rather than directly on wall efficiency, insect resistance, durability and architectural inter- weight.
