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/m^{3}

**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 m^{3}

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 |
