08-08-2020What is fineness test of cement? The test done for finding the fineness of cement by sieving the cement on the standard IS sieve is called the fineness test of cement. The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement.
