Final answer:
True. In a typical CMU wall, face-shell mortaring is used to provide structural stability.
Step-by-step explanation:
In a typical CMU (Concrete Masonry Unit) wall, face-shell mortaring is used, which implies that the mortar is placed.
Face-shell mortaring is a technique where mortar is applied to the face shells of the CMU blocks during construction. This helps to create a solid bond between the blocks, providing structural stability to the wall.
Therefore, the statement is true - in a typical CMU wall, face-shell mortaring is used.
