Anotace

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.
