Inverse analysis of moisture profiles for the assessment of moisture diffusivity of hybrid fiber reinforced UHPC

Popis výsledku v původním jazyce

Inverse analysis of experimental accessed moisture profiles is presented in the paper as an effective tool for the determination of moisture diffusivity of hybrid fiber reinforced Ultra High Performance Concrete (UHPC) exposed to high temperatures. The UHPC was provided with fiber reinforcement based on polyvinyl alcohol (PVA) and steel fibers. Analyzed material was characterized by its bulk density, matrix density, and total open porosity. Moisture profiles were measured on prismatic samples in 1-D vertical arrangement of water suction experiment. For moisture content measurement, gravimetric method was used. In order to analyze effect of high-temperature load on concrete performance, all the realized experiments were done for concrete samples exposed to laboratory temperature and to the temperatures of 800 °C and 1000 °C respectively. For calculation of moisture dependent moisture diffusivity, inverse analysis method based on the Boltzmann-Matano treatment was used.
