Question: 1 / 400

What is one consequence of excess moisture in concrete?

Heat retention

Delamination of leveling compound

Excess moisture in concrete can lead to delamination of the leveling compound, which is the correct response. This occurs because the presence of too much moisture can weaken the bond between the leveling compound and the concrete substrate. When moisture seeps through the surface, it can prevent proper adhesion, causing the leveling compound to separate from the concrete. This delamination can lead to further structural issues and surface defects.

While heat retention, increased structural strength, and enhanced durability might seem desirable, they are not typically associated with excess moisture in concrete. In fact, excess moisture usually has the opposite effect. It often leads to deterioration of the concrete and the materials that are applied to it, undermining the overall integrity and performance of the structure.
