Study on the Compaction Behavior of Fresh Concrete on Vibrating Table as a Result of Emission of Air Bubbles

Abstract

To predict the compaction behavior of fresh concrete by means of vibrating table, an analytical evaluation method was proposed. It is based on a few assumptions that fresh concrete is expressed by Newtonian fluid and compaction is accomplished by discharging air bubbles from the fresh concrete. This method was applied to the compaction tests of a fresh concrete for roller compaction during vibration by means of vibrating table, then efficiency of the method was confirmed.
