“…For example, face-shell bedding is a typical practice in North America and Australia (Page and Shrive (1988)), whereas full bedding is often used elsewhere (see Figure 7-4). The difference in construction practice is significant as it directly affects the capacity and failure modes of masonry when loaded in axial compression (Maurenbrecher (1980), Gaynor et al (1987), Nacus (1980)). That is, investigations (Maurenbrecher (1980), Gaynor et al (1987), Nacus (1980)) have shown that masonry prisms made with face-shell mortar bedding fail at significantly higher compressive stresses than those made with full mortar beddings.…”

Ratios of strength of fully bedded to face shell bedded prisms have been reported to range from 0.84 to 0.91 with a weighted average ratio of about 0.89 (Colville and Wolde-Tinsae (1991)) .…”
