The glazing on the face of a glazed CMU can add how much to the unit's face dimensions?

The correct answer is that the glazing on the face of a glazed concrete masonry unit (CMU) can add 1/8" to the unit's face dimensions. This addition is primarily due to the glazing process, which involves applying a layer of glass or a similar material onto the surface of the CMU. This layer not only enhances aesthetic value and provides a smoother finish but also increases the overall dimensions of the unit slightly.

Understanding the implications of this dimension change is crucial for masonry construction and design, as it affects how these units fit together in a wall assembly. Accurate knowledge of these specifications ensures that masonry work is performed correctly and that structural integrity is maintained.
