What is the minimum allowed width for a mortar joint in glass block construction?

2 inches
3 inches
4 inches
5 inches

The correct answer is: 3 inches

In glass block construction, the minimum allowed width for a mortar joint is set to ensure structural integrity and adequate bonding between the glass blocks. A mortar joint of 3 inches is standard because it allows for sufficient space to accommodate any discrepancies in block size, offers proper sealing against water infiltration, and provides enough mortar to ensure a strong adhesion. This width also facilitates the even distribution of forces across the blocks, which is essential given that glass is a brittle material. Maintaining this standard width helps in achieving a durable installation while also complying with building codes and best practices within the industry.
