Fremgangsmåde og indretning til komprimering af en blanding

摘要

Process for compacting and shaping a mixture, preferably a concrete mixture, in a mold comprises applying the movement of a continuous transversal wave onto the base of the mold to compact the mixture. An Independent claim is also included for an arrangement for carrying out the above process. Preferred Features: The movement is produced by periodically applying and temporally displacing by a phase forces for elastic deformation of the base surface onto regions of the base of the mold arranged a specified distance apart. The frequency of the wave is 30-150 Hz. Accelerations are produced which are 3-10 times the acceleration due to gravity.
