Structural CMUs that have one or more finished faces are known as what?

Structural concrete masonry units (CMUs) that have one or more finished faces are referred to as architectural CMUs. These units are designed not only for their structural capability but also for their aesthetic appeal. They are often used in visible areas of construction where aesthetics matter, such as exterior walls or decorative interior features.

The finish on these units can include various textures, colors, or patterns, making them suitable for applications where both strength and appearance are important. By integrating functional design with architectural quality, architectural CMUs can significantly enhance the visual aspect of a building while still providing the durable and load-bearing qualities typical of concrete masonry.

In contrast, the other types of CMUs mentioned serve different functions or specifications that do not emphasize a finished appearance suitable for architectural design.
