It is a lean mix of proportion is 1:3:6(C:FA:CA)

Answer / orient builders

1 4 8 means cement sand (fine aggregate) metal 20 mm (coarse
aggregate)respectively.
The ratio is based on volume and not in weight.
one bag of cement is 1.25 cubic foot
Therefore multiply the fine and coarse aggregate with 1.25.
Thus you have to use 1.25 cft of cement (one bag) and 5 cft
of sand and 10 cft of coarse aggregate.
As for sand is concerned bulkage allowance is to considered
according to which the quantity may slightly vary
