Correct answer: C. Both A. & B.
- A. Strength
- B. Abrasion resistance
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
Excess lime in silica-brick bonding increases the glassy bonding phase and weakens the brick, reducing both mechanical strength and resistance to abrasion. Hence both effects occur.
