How to perform cement finesse test and final setting time and initial setting time

Question

Accepted Answer

Cement finesse test measures the particle size of cement. Initial and final setting time tests measure the time taken for cement to set.

For cement finesse test, a sample of cement is sieved through a standard sieve and the residue is weighed.
The residue is then sieved through a finer sieve and the weight of the residue is again measured.
The difference between the two weights gives the fineness of cement.
For initial and final setting time tests, a sample of cement is mixed with water and a Vicat apparatus is used to measure the time taken for the cement to set.
The initial setting time is the time taken for the cement to partially set and the final setting time is the time taken for the cement to completely set.
