EVALUATION OF VIBRATING COMPACTION PROCESS FOR FRESH CONCRETE
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2009, Vol 54, Issue 3
Abstract
This paper is focused on the research performed upon the dynamic model for vibrating compaction of the placed fresh concrete. The influence of the internal viscosity factor changing upon the internal energy dissipated during the concrete structure hardening is put into evidence.
