Nordic evaluation of methods for testing fresh self-compacting concrete (NT TR 558)

NT TR 558

  • In this study a modified inter-comparison test was proposed for evaluating the precision of methods for testing fresh SCC whose properties are not identical from laboratory to laboratory or even from batch to batch. The modification includes collecting a number of sets of similar equipment and carrying out a local inter-comparison test in each laboratory by different operators, each operating a number of sets of equipment.
