How can extreme moisture impact masonry work?

• A. It can help in curing the mortar
• B. It may weaken the mortar when drying
• C. It does not affect the quality
• D. It speeds up the construction process

Answer: (B)

Extreme moisture can significantly impact masonry work by weakening the mortar. When there is an excessive amount of moisture, it can disrupt the balance of the cement and water in the mortar mix. As the mortar dries, if it has absorbed too much moisture, it may not achieve the intended strength due to improper curing conditions. Mortar requires a specific moisture level to cure correctly; if it is too wet, it can prevent the cement from chemically bonding properly as it hydrates. This incomplete curing can lead to a loss of structural integrity, causing issues such as cracking or reduced load-bearing capacity in the finished masonry. Therefore, the impact of extreme moisture is a critical factor to consider during masonry work to ensure that the final product meets safety and performance standards.
