Temperature Field Test and Numerical Simulation Research in Concrete under Cryogenic Temperature

Abstract:

The mechanical properties of concrete under cryogenic temperature (-165°C) are affected by the temperature field inside the concrete. This paper presents assumptions by adjusting the formulas of thermal conductivity (λ) and specific heat capacity (C), respectively under low temperature. Through ABAQUS, we simulate the temperature downward-upward processes and compare them with the test results. Finally, the research gets more reasonable formulas of λ and C, respectively under cryogenic temperature.
