Fineness test for cement is used to determine the particle size of cement particles. It is an important test in the process of manufacturing cement as the fineness of cement particles directly influences its strength and setting time. Test Procedure: 1. Take a 100 gram sample of cement and place it on a clean and dry 90-micron sieve. 2.

Fineness Test of Cement. Fineness test of cement is done to determine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods; 1. Sieving Method. 2.

The fineness modulus cannot represent the particle size distribution, but it is useful for measuring slight variations in the aggregate from the same source, i.e., as a day to day check. Based on the practical experience, the fineness modulus of fine aggregate should be between 2 to 3.5 and of coarse aggregate between 3.5 to 8.
