What requirement must a CMU wall adjoining another at a right angle meet?

• A. Be decorative
• B. Be secured
• C. Be anchored
• D. Be insulated

Answer: (C)

A Concrete Masonry Unit (CMU) wall that adjoins another wall at a right angle must be anchored to ensure structural integrity and stability. Anchoring provides the necessary connection that helps resist lateral forces that might cause the walls to move or separate under various loads such as wind or seismic activity. This connection is vital for maintaining the overall strength and performance of the masonry system, particularly in projects where multiple walls form part of a larger structure. In contrast to anchoring, decorative finishes, insulation, or merely securing do not address the specific structural requirements needed for a CMU wall that meets another at a right angle. While insulation and decorative elements may provide benefits such as thermal performance or aesthetic appeal, they do not contribute directly to the structural stability that anchoring provides. Thus, anchoring is the essential requirement in this context.
