Spalling is defined as what?

Spalling is defined as what?

• A. A crack caused by cold temperatures
• B. Pocket of concrete that has crumbled to fine particles through exposure to heat
• C. A decorative finish
• D. A surface stain

Answer: (B)

Spalling describes the concrete surface breaking away in chunks or a powdery layer, forming pockets where material has crumbled. This happens when heat or rapid temperature changes cause moisture inside the concrete to turn to steam and push the surface apart, leading to crumbling particles. The given definition matches this by describing a pocket of concrete that has crumbled into fine particles due to exposure to heat. It isn’t simply a crack from cold, nor a decorative finish or a stain.
