First, consider the mix ratio that you are going to use for the concrete mixture, refer to the below table for different mix ratios:
How to calculate Cement Bags In 1 Cubic Meter
Consider the required mix ratio, Here we have considered M20 mix 1:1.5:3
Some constant Values to know before cement quantity calculation
Density of cement = 1440 kg/m3
Weight of 1 bag of cement = 50kg
Dry Mix = 1.55
Cement Calculation
Volume of cement = (Cement part / cement +sand+aggregate)x Dry volume
Volume of cement
= (1/1+1.5+3)x1.55
=0.282 m3
Now multiply volume of cement with cement density
= 0.282 x 1440
= 406.08 kg
To convert kg into a number of bags dived the total weight of cement by weight of each bag
= 406.08/50
= 8.12 Bags
So for a nominal mix of 1:1.5:3, a total of 8.12(or 9) bags of cement Bags are required for 1 cubic meter.
| Grades of Concrete | Concrete mix ratios(Cement:Sand:Aggregate) | Cement in Cu.m | Cement in Bags |
|---|---|---|---|
| M5 | 1:5:10 | 0.097 | 2.79 |
| M7.5 | 1:4:8 | 0.119 | 3.43 |
| M10 | 1:3:6 | 0.155 | 4.46 |
| M15 | 1:2:4 | 0.221 | 6.37 |
| M20 | 1:1.5:3 | 0.282 | 8.12 |
| M25 | 1:1:2 | 0.387 | 11.16 |
| M30 | According to the design mix |
