Test Sieve Verification and Calibration
Test sieves are fundamental tools used to determine the particle-size distribution of aggregates, soils, concrete, asphalt mixtures and other bulk materials. The dimensions of sieve openings directly influence the reliability of test results and therefore the quality and safety of construction works.
