  • What is a concrete masonry unit?
    Most specification writers, architects, engineers and builders, commonly refer to concrete masonry units as CMU’s or concrete block. The units are formed in a block machine, which uses vibration and pressure to form the blocks from a relatively dry mix with a low water/cement ratio.

    What are the standards for concrete masonry units?
    The most widely used standards for specifying concrete masonry units in the United States are published by ASTM International. These ASTM standards contain minimum material and property requirements that assure quality performance.

    What are scored concrete masonry units?
    Scored concrete masonry units are manufactured with one or more vertical scores on the face to simulate additional mortar joints in the wall (FIGURE 14). Scored units reduce the perceived scale of the masonry while still allowing construction using full sized units.

    How much does a concrete masonry unit weigh?
    (See section 1.2.3 - Cost Guide) Concrete masonry units are made with either standard weight or lightweight aggregates, or a combination of the two. A loadbearing concrete block of 200x200x400mm nominal size will weigh approximately 18kg when made with standard weight aggregates, and 15kg when made with semi-lightweight aggregate.

    What is the minimum compressive strength of concrete masonry units?
    This provision avoids excluding units intentionally manufactured with reduced webs, including bond beam units and open-end block, where grout fulfills the structural role of the web. The minimum net area compressive strength of concrete masonry units complying with ASTM C90 is 2,000 psi (13.8 MPa).

    Are all concrete masonry units structurally designed the same?
    All concrete masonry units meeting the requirements of ASTM C90 (REF. 1) are structurally designed in the same manner, even when their configuration varies. For example, a concrete masonry unit with a nominal height of 8 in. (203 mm) is analyzed the same as a unit with a nominal height of 4 in. (102 mm).
