Grout is the material used to fill in the space between individual masonry pieces.

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (A)

Grout is the cementitious material used to fill the spaces between masonry pieces, such as the cores of hollow blocks or gaps between units, helping to lock them together and create a solid, reinforced mass. This makes the statement true because grout purposefully occupies those voids to strengthen and stabilize the structure. Mortar, by contrast, is primarily used to bond units during initial construction, so grout’s role is filling the gaps after placement. The other options don’t fit because grout isn’t never used for gaps, nor is it only sometimes applicable in a way that contradicts standard masonry practice.
