Concrete Strength Calculator
Calculate compressive strength from crush test load and compare against design strength.
How to Use the Concrete Strength Calculator
- Enter the failure load from the crush test in kN.
- Enter the specimen cross-section area in mm².
- Enter the design strength in MPa.
- Review compressive strength and pass/fail status.
Casos de Uso
- •Concrete cylinder testing
- •Quality control on site
- •Structural strength verification
