Answer / rajarshi basu

Keeping the casting of piling in mind on site,it would be
foolish to answer this kind of question as the concrete used
for casting is RMC where we dont get to know the proportions
of mixes the mix designer has used to design the specified
concrete.

Otherwise it is too simple to calculate from Nominal mix design

Answer / ameen chouhan

The ratio 1:1 is micro piles and 22bags per cum

Answer / s.r.shiradhonkar

vol of pile is 0.63 cum
Material required
Metal (0.80 cum/cum of concrete)i.e 0.8*0.61=0.488 cum
Sand (0.40 cum/cum of concrete) i.e 0.4*0.61=0.244 cum
cement(0.40 cum/ per cum), (as cement sand ration mentioned
1:1). cement required= 0.4*.0.61=.244 cum. 1bag of 50 kg
have volume 0.035 cum. there for bags required=0.244/.035=
7 bags.

Answer / dushyant bansal

For 1:1 Cement sand ratio
total volume of either will be same as the ratio will be
1:1
and Sand will cover about 80% volume hence 0.8*0.61=
0.488cum
and same vol of cement.

Answer / sjtbehera

8. Volume of pile -.61m³
If you given cum your ratio is 1:1:2 not 1:1
Total ratio=1+1+2 = 4 so cement = .61/4=.1525m³= 4bags
Sand=.1525cum
Agg.=.1525*2=.305m³
