Required water for 1 bag cement = 0.45 × 0.0353 = 0.0159 cum. Where volume of 50 kg cement = 0.0353 cum. 1 m3 water = 1000 Litre. Required water for 1 bag cement=0.0159 × 1000 = 15.9 Litre. ∴ Required water for 6.33 bags cement = 6.33 × 15.9 = 101 Litre. Summary: Cement = 6.33 bags. Sand = 0.44 cum. .
