weight when w/c ratio is 0.60 and
unit weight of concrete is
2,400 kg/m3.

(B) 205 L
(C) 245 L
(D) 285 L
​

Answer 1

The total water required in the mixture is 206 litres .

Explanation:

• The total quantity of cement in 1 m^3 concrete is 2400/7 = 343 kg
• Now, your water cement ratio is 0.6
• Now multiply the quantity of cement by the water cement ratio

343 x 0.6= 206 kg of water.

As we know that 1 kg of water is equal to 1 litre

Therefore,\

206 Kg = 206 Litres

Thus the total water required in desired mixture is 206 litres .
