Abstract

The purpose of this study is to examine the impact of waiting before re-vibration. and variable time duration for vibration and re-vibration operation of structural response for flexural reinforced concrete beams and using Ordinary Portland Cement-type 1, with w/c ratio of 0.4, and a greater number of re-vibration time lag intervals ranging from half an hour to two hours to evaluate the impact of re-vibration on the mechanical properties of concrete with different time duration of vibrations ranging from 15 to 60 seconds. The experimental schedule includes a total of 28 twenty-eight rectangular reinforced concrete beams of dimension (125 mm x 250 mm) and length of 1500 mm was prepared for this work. Using the re-vibration technique in construction of structural members is expected to improve the structural properties of the beams, and cracking. The result of the waiting time before re-vibration must be investigated and time duration of vibrations on the structural response of flexural reinforced concrete beams to establish and verify the best process to apply this technique.
