Q36

The nominal size of the modular brick is

A.
190 mm × 90 mm × 80 mm
B.
190 mm × 190 mm × 90 mm
C.
200 mm × 100 mm × 100 mm
Answer
D.
200 mm × 200 mm × 100 mm

Answer: Option C

Solution

Answer: Option C
Solution:
Modular bricks are standardized bricks used in construction to maintain uniformity and ease of calculation in masonry work.

The actual size of a modular brick is typically 190 mm × 90 mm × 90 mm.

However, when the thickness of mortar joints (usually about 10 mm) is included, the nominal size becomes 200 mm × 100 mm × 100 mm.

This nominal size ensures proper bonding and modular coordination in construction.

Therefore, the correct answer is 200 mm × 100 mm × 100 mm.
