Its a density of cement.

Antil said:   10 years ago
This is not a density of concrete. It is density of cement = 1440 kg/m3.

Thank you all for providing the clear solution.

Clear cut solution:

A cement bag contains 35 liters of cement,

35 x 1 : 35 x 3 : 35 x 6.
= 35 : 105 : 210.

50 kg of cement - 35 lit volume.
1:3:6
35 lit cement : 105 lit sand : 210 lit c.a.

Thanks @Baloch.

Your explanation is very simple & easy to understand.

1kg = 0.7 liters.
50kg cement - 35liters.
3*50kgsand-150 * .7 = 105liter.
300kg aggregate-300*.7 = 210 liters.
