Standard Test Method for Fineness of Hydraulic Cement by Air Jet Sieving at 45-µm (No. 325)
SIGNIFICANCE AND USE
5.1 This test method provides data for assessing compliance where specifications limit the amount of material retained when sieved on a 45-µm (No. 325) sieve.
SCOPE
1.1 This test method covers the determination of the fineness of hydraulic cement by means of air jet sieving using a 45-µm (No. 325) sieve by Air Jet sieving.
1.2 The values stated in SI units are regarded as the standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Test Method
4.1 A known mass of hydraulic cement is placed on a test sieve that is inserted in the sieve holder of the air jet sieve apparatus.
Air from a slowly-rotating nozzle located beneath the sieve passes through the sieve to fluidize the sample for a predetermined
period of time. The exit air flow removes undersized particles downward through the test sieve to a vacuum canister. The mass
of hydraulic cement retained on the test sieve is determined, and the percent passing the test sieve is calculated.
