This method, very popular in Scandinavia, is used for mix design and quality control mainly in concrete products plants, where low workable and zero slump concrete is used (for such products as hollow-core slabs, tubes and paving blocks).
The method is used for: mix design simulating selected production processes specimen preparation for strength test (fresh and cured) research of mix related phenomena (workability, curing time, admixtures etc.).

Compaction is achieved by the simultaneous application of a low-static compression and a shearing action, which results in the motion of the centre-line of the test piece, which generates a conical surface of revolution while the ends of the test piece remain approximately perpendicular to the axis of the conical surface.

The machine is equipped with 100 mm diameter mould with stripping accessory and process­es in real time the evolution of sample density versus the number of cycles and plots the compaction curve.

It’s possible to upgrade the machine in order to measure the Shear during compaction in kN/ m2. Shear is a measuring parame­ter useful for a deeper selection/ dosage and tuning of no-slump concrete components. For in­stance, a very small change in water and plasticizer can shift no­tably the positioning of max shear value along the compaction curve. Increase of water and plasticizer generally shift the max shear val­ue toward the first gyratory cycles; instead the decrease of water and plasticizer shift the max shear to­ward the end of compaction.

  • Ideal for mix design of the various types of No-Slump Concrete mixtures requested for production of: paving blocks, concrete paving slabs, rolled compaction concrete, masonry blocks, curbstones, roofing tiles, sewage pipes, hollow core slabs, structural members, extruded fresh concrete elements, concrete road construction with slip form paving finishers, in general directly stripped products.
  • Conform to Scandinavian standard NT BUILD 427 – Concrete, fresh: Compactability with IC-tester (intensive compaction tester).
  • Load cell fitted directly on the vertical actuator for accurate load measurement and feedback control
  • User defined axial stress and speed of rotation
  • Easy control using the integrated 7″ colour touch-screen control panel or connected PC.
  • Real-time direct shear and torque resistance measurement.  Automatic calculation of the compaction energy, an important parameter for Research (optional).
