Moisture, Absorbed

Definition

Moisture that has entered a solid material by absorption and has physical properties not substantially different from ordinary water at the same temperature and pressure.

Purpose

Absorbed moisture impacts the physical properties of materials, such as wood and concrete, by altering their weight, strength, and dimensional stability. Understanding absorbed moisture is crucial for ensuring material performance and durability in various environmental conditions.

Examples of Use

• Wood: Moisture absorbed in wooden structures can lead to swelling, warping, or rotting.
• Concrete: Absorbed moisture in concrete can affect its strength and durability, especially in freeze-thaw conditions.
• Insulation materials: Moisture absorption in insulation can reduce its effectiveness and lead to mold growth.

Related Terms

• Moisture Content: The amount of moisture contained in a material, usually expressed as a percentage.
• Hygroscopic: The ability of a material to absorb moisture from the air.
• Desorption: The process by which a material releases absorbed moisture.

Notes

• Monitoring and controlling absorbed moisture are essential to maintain the integrity and performance of materials.
• Moisture barriers and protective coatings can be used to minimize moisture absorption.
• Regular inspections help identify and mitigate moisture-related issues before they cause significant damage.
