State whether the following is true or false.
A flash set can be overcome by remixing in the same way as a false set.

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

Answer: B

Flash set involves genuine hydration of the aluminate phase and cannot be reversed by mixing. Only false set, which is a physical stiffening from recrystallised gypsum, responds to further working. The remedy for one is useless against the other.
