CSA A456.2-A3-98 PDF Download

CSA A456.2-A3-98 is a standard that specifies a test method for determining the fineness of cement through wet sieving. The purpose of this standard is to provide a standardized procedure for evaluating the particle size distribution of cement particles. The test utilizes a 45 pm calibrated sieve, which is used to separate the cement particles based on their size.

The standard also includes a procedure for calibrating the sieve. This is an important step to ensure accurate and consistent results. By calibrating the sieve, any variations in the sieve openings can be identified and accounted for, allowing for precise measurements of the cement particles.
