This report covers the state of the art of processes that take place in the consolidation of fresh concrete during vibration.

These processes, rheological and mechanical in nature, are discussed to provide better understanding of the principles. The first chapter presents the historical developments relative to consolidating concrete. The second chapter deals with the rheological behavior of concrete during consolidation and the associated mechanisms of dynamic compaction. The third chapter presents the principles of vibratory motion occurring during vibration, vibratory methods, and experimental test results. Continuing research in the field of concrete vibration, as evidenced by the extensive literature devoted to the subject, is addressed.
