How to calculate the number of cement bags in one cubic meter of concrete using concrete ratio 1:2:4

Total ratio = 1+2+4 = 7
Dry volume of 1m³ of concrete = 1.54x1m³=1.54m³

Volume of cement by ratio = 1/7 x 1.54 = 0.22m³
Volume of sand by ratio = 2/7 x 1.54 = 0.44m³
Volume of coarse aggregate (Gravel) by ratio = 4/7 x 1.54 = 0.88m³

Weight of cement = Density of cement x volume of cement = 1440 x 0.22m³ = 316.8kg.

If one bag of cement is 50kg, 316.8kg will give 316.8/50 = 6.34bags per cubic meter.

Weight of sand = Density of sand x volume of sand. If density of sand is taken as1550kg/m³; weight of sand = 1550 x 0.44 = 682kg = 0.682 tons.

Weight of coarse aggregates (gravel) = Density of gravel x volume of gravel. If density of gravel is taken as 1650kg/m³; weight of gravel = 1650 x 0.88 = 1452kg = 1.452tons.

If you do similar calculations using ratio 1:3:6, you'll get approximately 4.44bags per meter cube for cement. 716kg(0.72tons) for sand and 1524.6 (1.52tons) for gravel.
