Final answer:
The term for a brick dimension that includes space for a mortar joint is the Nominal Dimension. It's larger than the brick's actual dimensions to accommodate for mortar. (option 1)
Step-by-step explanation:
The term used to describe a brick dimension that is larger than the actual dimension to account for the thickness of a mortar joint is the Nominal Dimension. This includes the size of the brick itself plus the space for the mortar joint, which provides the necessary adhesion between bricks. The actual dimensions are the physical measurements of the brick without accounting for additional space for the mortar.
For instance, if a brick is nominally labeled as 200 mm × 100 mm, the actual brick size might be slightly smaller to accommodate mortar joints, say 190 mm × 90 mm. The difference between the nominal and actual dimensions accounts for the space the mortar will occupy. This practice simplifies construction processes and helps achieve the intended structural dimensions.
The term used to describe a brick dimension accounting for the thickness of a mortar joint is the "Nominal Dimension." This practice is crucial in construction, allowing for accurate planning and assembly of structures by considering the space occupied by mortar joints.
