Answer / surya v kuchibhotla

If you are considering 1:4:8; per each cubic meter you have
to arrive the quantities as under.
If 1+4+8= 1cum (dry mix); then
cement quantity will be 1/13 = 0.077 cum;(2.2 Bags of 50kg)
Sand Quantity will be 4/13= 0.31 cum and
the Quantity of Coarse aggregate shall be 8/13=0.62 cum.

But, the volume of dry concrete will be 1.5 times
(approx)the volume of wet concrete. So, if you want to
prepare a cum of wet concrete, multiply the above values by 1.5.
