GB/T 1345-2005 "Test Method for Fineness of Cement - Sieving Method" specifies the methods for determining the fineness of cement using the sieving method, including the negative pressure sieving method, the water sieving method, and the manual dry sieving method. This method characterizes the particle size distribution of cement by measuring the residue on the standard sieve (i.e., the percentage of particle mass that fails to pass through the sieve mesh).
