The ASTM C430-17 standard test method is used to determine the fineness of hydraulic cement by a 45 μm (No. 325) sieve. This method uses a sieve test to evaluate the size distribution of cement particles, which in turn reflects the fineness of cement. Cement fineness is an important factor affecting its hydration reaction rate, strength and Miscellaneous performance. This standard provides cement manufacturers, quality control laboratories and the construction industry with a simple and reliable fineness detection method to help ensure that the mass of cement products meets the requirements of use.
