What additional size must be considered to obtain nominal dimensions?

• A. Block width
• B. Joint size
• C. Block length
• D. Block height

Answer: (B)

To determine nominal dimensions in masonry, it is essential to consider joint size, as this accounts for the mortar used between the blocks. Nominal dimensions refer to the overall dimensions of a masonry unit, taking into account not just the block itself, but also the space that mortar joints occupy when the units are assembled. In masonry construction, each block has specific theoretical dimensions (nominal size), but due to the presence of mortar joints, the actual dimensions can vary. Mortar joints typically add thickness to the overall dimensions, thus affecting how the blocks fit together in the wall. Each block's width, length, and height may remain constant, but the joint size must be included to provide an accurate representation of how these blocks integrate into a complete structure. This is crucial for ensuring proper alignment, spacing, and overall structural integrity when constructing walls.
