State whether the following is true or false.
False set can usually be overcome by continued mixing without adding water.

  • A.True only at large scales
  • B.False only at small scales
  • C.True
  • D.False

Answer: C

Correct answer: True

The stiffness comes from a fragile network of secondary gypsum crystals, not from the cement setting, so continued mixing breaks it down and the paste becomes workable again with no water added. That is exactly what distinguishes false set from flash set, which is genuine and irreversible.
