摘要：A method of measuring the compactibility of a fresh concrete mass, for obtaining information of the applicability of the mass with respect to the strength properties of the cast product. A sample (20) having a determined weight (m) is taken from the mass and compressed in two opposite directions with a constant force (P) and subjected to a shearing compaction between two slanting planes (13, 14) which extend in parallel with each other and alter their positions through rotation. The volume (V, Vt) of the sample is determined at the beginning of the compaction and after a pre-determined compaction work, whereafter the volume change of the sample is compared with experimentally defined limit values. The apparatus comprises a compacting device for subjecting the sample in a container to a shearing compaction, and means for maintaining the sample under compression during the compaction.
