Compaction of concrete or similar plastic mass units - has amplitude of vibrational action reduced to zero at end of compaction process

摘要

The system is for compaction of constructional units made of e.g. concrete. It comprises a vibratory table system with a former framework and compression die system with vibratory impaction motion exerted upon it. The amplitude of the vibrational action and the resultant lift of the compaction impacts is diminished in a continuous or stepwise manner to zero at the end of the compaction process. The compaction is ended by through application of static pressure.
