With the help of the Concrete Mix Calculator, you can calculate the required quantities of cement, sand, and aggregate for any concrete grade. This calculator is highly useful for site engineers, contractors, quantity surveyors, and civil engineering students.
How to Use?
Grade of Concrete
- 10 = M10 (1:3:6)
- 15 = M15 (1:2:4)
- 20 = M20 (1:1.5:3)
- 25 = M25 (1:1:2)
Quantity
Enter the required volume of concrete in cubic meters (m³).
The calculator will automatically calculate the quantities for Cement (Bags), Sand (m³), and Aggregate (m³).
Example
Grade = 20 (M20 Concrete)
Quantity = 5 m³
Result (Approximate):
- Cement = 40 Bags
- Sand = 2.8 m³
- Aggregate = 5.6 m³
Common Concrete Grades
| Grade | Mix Ratio | Typical Use |
| M10 | 1:3:6 | PCC Work |
| M15 | 1:2:4 | Levelling Course |
| M20 | 1:1.5:3 | RCC Slab, Beam, Column |
| M25 | 1:1:2 | Heavy RCC Structures |
