How Do You Spell SPALLED?

Pronunciation: [spˈɔːld] (IPA)

The word "spalled" is spelled with two L's, which may initially seem like an error to those unfamiliar with its origins. However, the spelling can be explained through its IPA phonetic transcription: /spɔːld/. The long "o" sound represented by the phonetic symbol "ɔː" is a result of the word's Old English roots. While the double L might appear redundant to modern English spelling conventions, it accurately reflects the historical spelling and pronunciation of the word.

SPALLED Meaning and Definition

  1. The term "spalled" refers to a phenomenon in material science and engineering, commonly associated with concrete or masonry structures. The verb "spalled" describes the process of a material, typically a brittle substance like concrete or stone, breaking apart or chipping due to extreme stress or pressure. This can occur as a result of various factors, such as freeze-thaw cycles, chemical reactions, excessive loads, or impact forces.

    When a material spalls, the surface layer or fragment cracks and separates, often revealing a rough, irregular texture underneath. This can compromise the integrity and durability of the structure, as the protective layer that shields the inner layers from external elements is compromised. In some cases, spalling can lead to progressive deterioration and structural instability.

    Spalling is a common issue in concrete structures, particularly in regions with harsh climates or exposure to saltwater. It often manifests as flaking, peeling, or chipping of the outer layer, gradually exposing the underlying layers to further degradation. To mitigate spalling, various protective measures can be implemented, such as using appropriate construction techniques, incorporating reinforcement, or applying surface treatments like sealants or coatings.

    In summary, "spalled" refers to the breaking apart or chipping of a brittle material due to stress, pressure, or environmental factors. Understanding spalling is crucial for ensuring the longevity and safety of concrete and masonry structures.

Etymology of SPALLED

The term "spalled" has its origins in the Middle English word "spalden", which meant "to chip or break into small fragments". This word is derived from the Old Norse word "spǫld", which means "wooden chip" or "splint". Over time, the meaning of "spalled" expanded to refer to the process of breaking or chipping in general, often used to describe damages to materials such as concrete or metal.
