AS 3583.1:1998 (R2016) PDF Download

AS 3583.1:1998 (R2016) is a standard that provides a specific method for determining the fineness of supplementary cementitious materials. The purpose of this standard is to ensure consistency in the measurement of fineness, which is an important physical property of cementitious materials.

The standard specifies the use of a 45 micrometre sieve for the wet sieving process. Wet sieving involves suspending the cementitious material in water and passing it through the sieve to separate the fine particles from the coarse particles. The retained material on the sieve is then dried and weighed to determine the percentage of material that passes through the 45 micrometre sieve.

By establishing a standardized method for determining fineness, this standard helps ensure that supplementary cementitious materials meet the required quality and performance specifications. It allows for accurate comparison and assessment of different materials, enabling users to make informed decisions regarding their suitability for use with Portland and blended cement.
