Hydrating concrete produces significant amount of hydration heat, which causes several problems in massive concrete elements. Multiscale simulation helped to find an optimal position of cooling pipes and cooling regime on an arch of Opárno bridge, Czech republic. The bridge was built during 2008-2010 with the arches spanning 135 m, see Figures. | Hydrating concrete produces significant amount of hydration heat, which causes several problems in massive concrete elements.
