What is the quality of aggregate that resists weathering known as?

• A. Durability
• B. Soundness
• C. Stability
• D. Integrity

Answer: (B)

The quality of aggregate that resists weathering is known as soundness. Soundness refers to the ability of aggregate materials to withstand the effects of environmental factors, such as moisture, temperature changes, and other weather-related conditions. It is particularly significant in ensuring that the aggregates maintain their strength and integrity over time, especially in concrete used for structures exposed to harsh weather. This quality is assessed by subjecting the aggregate to conditions that simulate weathering, such as freeze-thaw cycles, and evaluating how much of the material is lost or degraded. A sound aggregate will demonstrate minimal change, ensuring that it remains effective in construction applications. In this context, durability refers to the overall lifespan and resistance to various forms of deterioration, whereas stability pertains to the ability of the aggregate to retain its shape and position under load. Integrity can imply the overall condition and structural soundness of materials, but it is not specifically a term used to denote the resistance to weathering like soundness is.
