"Now by referring mix design sheet, you can calculate required quantity of material by multiplying it with total volume of concrete required.
I will just show you how you calculate cement
300 Kg/cum x 100 cum = 30000 Kg = 30 MT
Like this you can calculate all materials."
More over, after calculating the bulk materials in tons, if the transporter/store needs the information by volume like cu-ft/cu-m, then finding the bulk density and convert to volume.
For Example,
1. Sand for 1 cum. 950 Kg. For 100 Cum 95000 Kg or 95 Tons.
Weight of sand in 30 lit bulk density cylinder is coming around 48 Kg means, 48/30= 1.6 kg per litre.
For 1 Cum, 1600 kg per cum.
For 1 Cum 35.315 Cft, that means 1 Cft = 45.3 Kg.
So 95000/45.3= 2097 Cft sand required.
2. Directly 1 Cft = 28.317 lit.
So, 1.6 x 28.317 = 45.30 Kg per cft.
3. If bulk density cylinder is not available, simply we can use Mason's farma which is 1.25 cft.(12' x 12' x 15")
If the weight comes, 56.6 kg in that farma, 56.6/1.25=45.30 kg / cft.
WE NEED TO CONSIDER MOISTURE CONTENT IN SAND WHILE REACHING AT SITE.
MAXIMUM 10 TO 15% OF MOISTURE IS COMING ALONG WITH TRANSPORT.
(SIMPLY BULKAGE)
SO WE NEED TO ADD THAT 10 TO 15% ALSO WHILE ARRANGING THE SAND FOR CONCRETE WORK.
