2.7.3 Bond Patterns in Concrete Masonry (Block) Walls
As in brick walls, the two most commonly used bonds are the running bond and the
stack bond. Running bond may be half running bond or one-third running bond. Concrete
masonry units are available in many thicknesses. In many cases, a variety of architec-
tural effects can be obtained by a carefully planned mixing of these units. In addition to
running and stack bond, concrete block can also be laid in diagonal and random pat-
terns to produce almost any architectural and visual effects. Structural aspects of bonds
in concrete masonry are discussed in Ref. [2.49], which are summarized in Chap. 6.
Ref. [2.1] illustrates 42 patterns for concrete masonry walls; some examples are shown in
Fig. 2.40.
