Water cement ratio is

 [A]. volume of water to that of cement [B]. weight of water to that of cement [C]. weight of concrete to that of water [D]. volume of concrete to that of water [E]. both (a) and (b) of the above.

Explanation:

No answer description available for this question.

 William T said: (Nov 25, 2016) Is it only weight of water to that of cement?

 Vikas said: (Dec 11, 2016) How it could be both? Explain clearly.

 Prashant Dwivedi said: (Apr 18, 2017) The correct answer is only B.

 Meet Kotadia said: (Jun 9, 2017) I think the answer is B.

 Dhanu said: (Sep 8, 2017) Weight = unit wt * vol. so A and B correct.

 Ajay said: (Nov 7, 2017) Weight = Unit Weight x Vol. Water Unit Weight = 1000 Kg/m3. But Cement Unit Weight = 1440 Kg/m3. So, 1000 Kg Water = 1 m3 Water. But, 1440 Kg Cement = 1m3 Cement. So, I think Option B is Correct. Weight of Water to Weight of Cement.

 Manoj said: (Nov 26, 2017) Only B answer is correct.

 Mohit said: (Jan 3, 2018) In small work, we measure in volume. And in mass work, we measure in weight to eliminate the bulking of sand. Therefore E is correct.

 James said: (May 22, 2018) By weight only. So, the correct Answer is B.

 James said: (May 22, 2018) By weight only. So, the correct Answer is B.

 Ali Zafar said: (Dec 5, 2019) Actually 1m3 of the volume contain 1000 kg of water or 1000 liters of water. So both weight and volume will be correct.

 Bapi Mandal said: (Jul 12, 2020) The correct answer is only option B.

 Pratik Pakhare.. said: (Sep 14, 2020) Answer B is correct. Because, Water : 1000 kg -> By weight. 1m3 -> By Volume Cement : 1440 kg-> By weight 1m3 -> By Volume And the Ratio : 0.694 : 1 Both rations are not same So that the answer E is definitely wrong. The Density of these both i.e. water & Cement is different, therefore w/c ratio cannot be calculated by using its volume so, the ans. A is also wrong. Finally, B is the correct answer.

 Bairagi said: (Sep 25, 2021) W/c ratio. Weight of water to Weight of cement.
