Which aspect is critical for ensuring the longevity of CMU structures?

• A. Proper ventilation
• B. Frequent painting
• C. Regular feeding
• D. Moisture control

Answer: (D)

Moisture control is critical for ensuring the longevity of Concrete Masonry Unit (CMU) structures because excess moisture can lead to a variety of issues, including mold growth, degradation of materials, and structural deterioration. CMUs can be susceptible to water infiltration, which may cause freezing and thawing cycles that weaken the masonry over time. Proper moisture control techniques, such as installing drainage systems, using moisture barriers, and ensuring proper site grading and landscaping, help to maintain the structural integrity of CMU walls. By managing moisture effectively, one can prevent these harmful conditions, thereby extending the lifespan of the CMU structure and reducing maintenance costs over time.
