Concrete Thermal Expansion/Contraction CalculatorEstimate crack potential from temperature changes in concrete structures. Original Length (L₀) meters (m)feet (ft) Coefficient of Thermal Expansion (α) (?) Typical for concrete: 5.5×10⁻⁶ /°F or 10×10⁻⁶ /°C. Varies with aggregate type. ×10⁻⁶ /°C×10⁻⁶ /°F Enter value as e.g., 10e-6 for $10 \times 10^{-6}$. Initial Temperature (Tᵢ) Celsius (°C)Fahrenheit (°F) Final Temperature (Tբ) Celsius (°C)Fahrenheit (°F) Optional Properties (for Stress & Crack Assessment) Modulus of Elasticity (E) (?) Typical for normal weight concrete: 25-35 GPa or 3600-5000 ksi. GPapsiksi Tensile Strength of Concrete (fₜ) (?) Typically 8-15% of compressive strength. E.g., 2-4 MPa or 300-600 psi.
