Modulus of Elasticity of Concrete Calculator
Estimate the deformation of concrete under load for structural cracking analysis. Based on ACI 318 and Eurocode standards.
MPa
Typical range: 20-50 MPa for normal concrete
kg/m³
Normal weight concrete: 2300-2500 kg/m³
About Modulus of Elasticity of Concrete
The modulus of elasticity (Ec) is a measure of concrete’s stiffness. It represents the ratio of stress to strain in the elastic range of deformation and is crucial for:
- Deflection calculations
- Crack width estimation
- Structural analysis
- Design of reinforced concrete members
Common Formulas:
ACI 318-19: Ec = 4700 × √(f’c) MPa (for normal weight concrete)
Eurocode 2: Ec = 22 × (fcm/10)0.3 GPa where fcm = fck + 8 MPa
