Abstract: 

The present work is aimed at studying the effect of re-vibration on the compressive strength of concrete using 53 grade Ordinary Portland Cement, with wide range of w/c ratios varying from 0.35 to 0.7 and with more number of re-vibration time lag intervals ranging from ½ hour to four hours. The effect of re-vibration on the density of concrete is also studied. The results have shown that the compressive strength of the concrete with various w/c ratios have increased up to certain time lag interval i.e. within the initial setting time (IST) and decreased thereafter. The percentage increase in the compressive strength also nearly followed the above trend.
