Discussion
State whether the following is true or false.
Grinding cement finer improves every property of the finished product.
Answer: A
Correct answer: False
Fineness is a trade rather than an improvement. Finer cement gives higher early strength but also higher water demand, greater heat of hydration, a shorter shelf life through prehydration, more shrinkage, and a sharply higher grinding cost. The optimum is a balance, and it differs for each cement type.
