State whether the following is true or false.
Clinker chemistry ends at the kiln outlet and cannot change afterwards.

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

Answer: C

Correct answer: False

Prehydration in storage, the addition of gypsum at the mill, and the reaction of alkalis with atmospheric carbon dioxide all alter the material after it leaves the kiln. Cement chemistry continues right up to the point at which the cement is used, which is why storage conditions and cement age are recorded.
