Answer / vikas d v

For 1cum ratio is 1:2:4

Adding 40-50% for wet concrete=1.5cum
VOL=1.5/(1+2+4)=0.214cum

cement=(0.214*1*(1440/50))=6.42bags
sand= 0.214*2=0.42cum
ca=0.214*4=0.856cum

Answer / sahilshah.civil@gmail.com

Cement : 6.6 Bag/Cu m
Sand : 0.51 Cu m/Cu m
Metal I & II : 0.98 Cu m/Cu m

Answer / rajasekhar

C.A = 0.92
Sand = 0.46
Cement = 0.23

Cement = 0.23 × 1440 = 331.2 Kgs = 6.624 bags ~ 7 bags.
Sand = cement × 2 = 331.2 × 2 = 662.4 kgs
C.A = cement × 4 or
Sand × 2 = 662.4 × 2 = 1324.8 kgs

Answer / fazcool2006

Cement=1.57 x 1/(1+2+4)=0.23 m3
0.23 x 1440=331.2 kgs /50= 6.624 bags,
sand = 1.57 x 2/(1+2+4)=0.45 m3
CA = 1.57 x 4/(1+2+4)=0.90 m3
