ENHANCEMENT ON DURABILITY OF CONCRETE STRUCTURES BY PREVENTING CRACKS DUE TO SETTLEMENT

THE PROPOSAL ON STANDARDIZATION OF USAGE OF SURFACE TAMPING VIBRATOR

Abstract

In reinforced concrete structures the surface layer has an important role to prevent external attacks which can make causes for corrosion of reinforcing bars. For realizing dense and non-porous concrete on unformed surfaces a surface tamping vibrator has been developed and applied in practical construction procedures. Effects of the equipment has also been verified by some experimental works with checking a ratio of flexunal strength of specimen between with and without tamping procedures. According to the practical and experimental results standard usages of the surface tamping vibrator is proposed for surface finishing to enhance durability of concrete structures.
