The water cement ratio in any cement-based material imparts a very important role. The determination of water cement ratio for quality control of fresh concrete, a new method has been developed named as “Electrical Resistivity”. This method isn’t very much popular because not much work has been done yet. In the present work a total number of 3 mixes has been prepared, three w/c ratio’s (0.4 ,0.5 & 0.6 ) has been taken. The water content is kept same during whole work (186kg/m3) as per IS 456:2000 guidelines. It is found that the resistivity of fresh concrete has a strong direct correlation with w/c. The resistivity probe used to measure the w/c is found within ±0.01 of the actual value for all the mixtures tested.
