Faster rate of drying of moulded refractories results in high _____________ of refractories?
Correct answer: A. Both B. and C.
- A. Both B. and C.
- B. Voids
- C. Shrinkage
- D. Green strength
Explanation
Rapid drying can produce nonuniform moisture removal, causing greater shrinkage and internal voids or cracks in the moulded refractory. Hence both voids and shrinkage increase.
