High alumina refractory compared to fireclay bricks have____________________?
Correct answer: B. High resistance to thermal shock and creep
- A. Less load bearing capacity
- B. High resistance to thermal shock and creep
- C. Low refractoriness
- D. Less resistance to slag attack
Explanation
High-alumina bricks withstand high temperatures, creep and slag attack better than ordinary fireclay bricks. The other choices contradict these advantages because high-alumina refractories have greater refractoriness and load-bearing capacity.
