Which weight is the least expensive?
Of the three weights, Normal Weight is the least expensive and Lightweight is the most expensive. Medium Weight is most popular (and therefore has greatest availability) for structural applications as its moderate weight and cost generally offer the best labor production to material cost ratio. For example weights per units and wall area, please see charts in Technical Articles, Average Weights.
What is the minimum face shell thickness for a masonry wall?
Minimum face shell & web thickness requirements of Standard Specification for Loadbearing Concrete Masonry Units, ASTM C 90-06 (ref. 8). These values apply to most currently available concrete masonry units. The 2006 edition of ASTM C 90 included slightly reduced minimum face shell thickness requirements for concrete masonry units 10 in. (254 mm) and greater in width. These smaller face shells result in slightly lower calculated wall weights for 10, 12-, 14- and 16-in. (254-, 305-, 356-, and 406-mm) units. Note that even though ASTM C 90-06 is not referenced in the International Building Code (ref. 9) until the 2009 edition, and in Building Code Requirements for Masonry Structures (ref. 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. 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.
What are the benefits of a concrete wall?
Concrete masonry walls provide a range of benefits, including structural integrity, fire and sound resistance, energy efficiency, insect resistance, durability and architectural interest. Many of these attributes are measured quantitatively, and often vary directly with the weight of the concrete masonry wall.
How thick is mortar?
All mortar joints are ⅜ in. (9.5 mm) thick. The mortar joint depth is equal to the thickness of the face shell or web on which it is placed (i.e., there is no excess mortar).
What is dead load?
Dead loads to resist uplift and overturning for high wind resistance. Additional wall properties are also impacted by wall weight, although estimates of these properties are based on concrete density or aggregate type, rather than directly on wall weight.
