ASTM C430-96(2003)

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

ABSTRACT
This test method covers hydraulic cement fineness tests performed using a sieve. The sieve frame should be made of a circular metal matching the specified dimensions, fitted with either a stainless steel woven-wire sieve cloth or an electroformed forced nickel sieve sheet. Both the nozzle and sieve shall not be subjected to corrosion by water. The nozzle and pressure gauge should also conform to the specified dimensions. This test method also covers sieve calibration and cleaning procedures.
SCOPE
1.1 This test method covers the determination of the fineness of hydraulic cement by means of the 45-μm (No. 325) sieve.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound equivalents of SI units may be approximate.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
