Author(s): H. A. Welton
Publication: Special Publication

Abstract:A brief discussion of consolidation of concrete aimed toward the users of concrete is presented to encourage the use of vibration in improving the quality of the finished product. Significant points leading to successful consolidation of quality concrete include the interrelationship of proportioning, mixing, placement, and application of the vibrator to break down mechanical stacking, eliminate unintentional air voids, reduce residual water content, and achieve densification and enhancement of the micro-structure of the concrete.
