What is the significance of "concrete moisture control" in construction?

Concrete moisture control is crucial in construction primarily because it addresses several key issues that can arise during and after the curing process. One of the significant aspects of moisture control is to avoid efflorescence and corrosion of steel reinforcement within the concrete.

When moisture levels are not properly managed, water can cause soluble salts present in the concrete or surrounding soil to be drawn to the surface, resulting in efflorescence, which can mar the appearance of the concrete. More critically, excess moisture can lead to corrosion of the embedded steel reinforcement. As steel corrodes, it expands, exerting pressure on the surrounding concrete, which can lead to cracking, spalling, and ultimately compromising the structural integrity of the concrete element.

By controlling moisture, construction professionals can ensure the longevity and durability of concrete structures, enhancing their performance and reducing maintenance costs over time. Preventative measures in moisture management not only protect the aesthetic qualities of the concrete but are also essential for maintaining the health of the entire structure.
