Description
The latest generation of rotary shear presses, the latest generation, the PCG 3, is able to meet the various requirements of European standard EN 12697-31 including compatibility studies and specimen production. and SHRP criteria.
The effect of compaction is obtained by the action of compression on a measuring cylinder which describes a cone at the summit confused with the center of the upper surface of this specimen and a half angle chosen on the basis of the standard or the desired test.
The process shall submit the materials constituting the specimen to the combined effects of a static compression force and mixing by shearing that guides the grains of the mineral skeleton. It allows for high densities with low compaction energies. The design of this machine is the result of 20 years of experience. It ensures very high stiffness of the specimen receptacle and its consistency on 360°, two parameters that contribute to the quality of the trial and its high reproducibility regardless of the characteristics of the materials tested.
