Abstract
Thermal cracks of massive concrete structures are affected by various factors. This paper reports the necessity of considering the heat radiation from concrete surface immediately after removing the mould when estimating the thermal cracks. On site measurements of heat radiation using thermography at seven sites were carried out. From the results of measurements, surface temperature was decreased until sixty minutes after removing the mould. The results of FEM analysis with this tendency for estimating thermal cracks, it became clear that the possibility of cracking is more increased than previous method.
