Except as noted in Table 2, units have nominal face dimensions of 16 in.When using dead loads for beneficial effects such as overturning resistance, it is advised that the lower wall weights based on ASTM C 90-06 be used. 10) until the 2008 edition, designers should be aware that many concrete masonry producers started complying with the reduced face shell requirements at a much earlier date.

9) until the 2009 edition, and in Building Code Requirements for Masonry Structures (ref. Note that even though ASTM C 90-06 is not referenced in the International Building Code (ref. These smaller face shells result in slightly lower calculated wall weights for 10, 12-, 14- and 16-in. The 2006 edition of ASTM C 90 included slightly reduced minimum face shell thickness requirements for concrete masonry units 10 in. These values apply to most currently available concrete masonry units. Minimum face shell & web thickness requirements of Standard Specification for Loadbearing Concrete Masonry Units, ASTM C 90-06 (ref.Weights listed in the tables are based on the following assumptions. Because of the small core size and resulting difficulty in consolidating grout, these units are rarely grouted. (102-mm) concrete masonry walls are not provided. Tables 1 through 8 list concrete masonry wall weights for 4 to 16 inch (102 to 406 mm) thick single wythe walls.

Wall weights are used directly to calculate: Many of these attributes are measured quantitatively, and often vary directly with the weight of the concrete masonry wall. Concrete masonry walls provide a range of benefits, including structural integrity, fire and sound resistance, energy efficiency, insect resistance, durability and architectural interest.
