Comparison information on the temperature control parameters for the two gravity dams.
| | Project | Coefficient of thermal expansion (10−6 × °C−1) | Adiabatic temperature rise of dam-body concrete (°C) | Self-grown volume deformation (120 days) (10−6) | Modulus of elasticity (90 days) (GPa) | Axial tensile strength (90 days) (MPa) | Ultimate tensile value (90 days) (10−4) |
| | This gravity dam | 9.0 | 26.3 | −20.0 | 20.2 | 2.03 | 1.09 | | Another gravity dam | 7.4 | 23.8 | −19.9 | 20.2 | 2.14 | 1.12 |
