Capacity of a refractory brick to withstand-sudden changes in temperature is denoted by the property called_________________?
Correct answer: A. Spalling resistance
- A. Spalling resistance
- B. Refractoriness
- C. Refractoriness under load (RUL)
- D. None of these
Explanation
Spalling resistance is the ability of a refractory to withstand cracking or flaking caused by sudden temperature changes. Refractoriness is resistance to high temperature, while RUL additionally refers to load-bearing ability at high temperature.
