Revision of C430-17 Standard Test Method for Fineness of Hydraulic Cement by the 45-µm (No. 325) Sieve


This standard is used for materials other than hydraulic cement. This method of fineness is widely used for evaluation of fly ash and natural pozzolans as outlined in C311 and C618. It is also used to evaluate ground-glass pozzolans in C1866. The following revisions update the scope to include other materials along with a disclaimer about use with materials other than cement.
