I think 50m3 concrete volume is the dry volume of concrete. So wet volume of the concrete is 1.54x50=77m3
for M20 concrete the aggregate ratio is 1:1.5:3
1. So, cement required= (1x77/5.5)=14m3=14x1440=20160kg=403.2 approx 404 bags
2. sand required = (1.5x77/5.5)= 21 m3
3. stone chips required = (3x77/5.5)= 42 m3
