Effects of High Temperature on Mesoscale Properties of Concrete
要約
This paper presents a complete experimental methodology for identification of parameters that are necessary for mesoscale numerical modeling and analysis of damage and degradation of concrete at high temperatures. For this purpose, a series of specialized mesoscale experiments are devised and carried out. The experiments target mechanical and fracture properties as well as characteristics of heat transfer of the main mesoscopic phases of concrete, namely, cement mortar, limestone aggregate, and their interface. The tests are conduced on samples that were exposed both to room environment and high temperatures. Results are presented in terms of temperature-dependent material characteristics.
