Q: In the Fineness test of cement of the following quantity is measured?
  • A. Specific surface area
  • B. Setting time
  • C. Mass Density
  • D. Specific gravity
Correct Answer: Option A - Fineness test – • Degree of fineness of cement is the measure the mean size of the grain in it and it is measure specific surface area of cement. • Fineness of cement is measured in the units of area/mass. OPC : 2250 cm²/g RHC : 3250 cm²g LHC : 3200 cm²/g PPC : 3000 cm²/g
