Cement (50 kg bags) vs Concrete Volume Needed

Formula

## Concrete Mix Design by Ratio A mix ratio specifies the proportional volumes of cement : sand : aggregate. ### Method 1. Dry volume = Wet volume x 1.54 (factor accounts for voids and compaction) 2. Divide dry volume by sum of ratio parts 3. Multiply each ratio part by the unit volume 4. Convert cement volume to bags: volume x 1440 kg/m^3 (bulk density) / 50 kg per bag Common ratios: 1:2:4 for M15 (general purpose), 1:1.5:3 for M20 (structural), 1:1:2 for M25 (high strength).

Esempio Risolto

1 m^3 of concrete at 1:2:4 ratio.

  1. 01Dry volume = 1 x 1.54 = 1.54 m^3
  2. 02Total parts = 1 + 2 + 4 = 7
  3. 03Cement = 1.54 x 1/7 = 0.220 m^3 = 0.220 x 1440 = 316.8 kg = 6.3 bags
  4. 04Sand = 1.54 x 2/7 = 0.440 m^3
  5. 05Aggregate = 1.54 x 4/7 = 0.880 m^3
