Measuring thermal properties of hydrating cement pastes
Critical inputs for heat transfer computations in concrete are the thermo-physical properties of the material as a function of time, including its density, heat capacity, and thermal conductivity. It is widely accepted that the conductivity and the heat transfer coefficient have an influence on temperature gradient along the concrete structure. Meanwhile, the exothermic phenomenon during the hardening process is mainly affected by the specific heat and density of concrete. While thermal and mechanical properties of the hardened concrete have been investigated in detail, only few studies of thermal properties fresh and young hardening concrete have been performed. Measurements of thermal properties of cement materials as heterogeneous, wet and porous materials by conventional steady-state methods can produce large errors. In order to avoid water migration during the long run-time of the steady thermal tests, transient measurement methods are preferable. In this paper, a transient plane source (TPS) method is applied to measuring heat capacities and thermal conductivities of hydrating cement pastes cured under both saturated and sealed conditions at room temperature.
