Therefore, a temperature was measured at certain points of a concrete specimen during the test and an adiabatic temperature rise was estimated with a numerically determined heat loss compensation. The determined adiabatic hydration curve was inserted into a numerical program, which is used to calculate a temperature field within the concrete element using a finite element method. Acomparison between numerically and experimentally determined values indicatesthe adequacy of the proposed numerical model. Moreover, the semi-adiabatic test proved to be an appropriate method to determine the adiabatic temperature rise.20112015-07-10 10:11:57Neznano32103UDK: 624.012COBISS_ID: 5533281OceCobissID: 257527552sl
