Q: The fineness of the cement and the development of cement strength are Compressive strength development due to cement and its fineness are in which relation with each other?
  • A. Insignificant
  • B. Inversely proportional
  • C. Directly proportional
  • D. Partially connected
Correct Answer: Option C - By increasing the fineness of cement the strength development of cement is increased. So, fineness of cement is directly proportional to the development of strength of cement. • Because surface area increase and hence reaction increase giving early strength.
C. By increasing the fineness of cement the strength development of cement is increased. So, fineness of cement is directly proportional to the development of strength of cement. • Because surface area increase and hence reaction increase giving early strength.

Explanations:

By increasing the fineness of cement the strength development of cement is increased. So, fineness of cement is directly proportional to the development of strength of cement. • Because surface area increase and hence reaction increase giving early strength.
