Properties of concrete at elevated temperatures

Conference ·
OSTI ID:5799243

This paper describes the ongoing testing program developed to determine the variations in the physical (thermal) and mechanical (strength) properties of limestone aggregate structural concrete, and the physical (thermal) properties of perlite insulating concrete exposed to sustained elevated temperatures up to 621/sup 0/C (1150/sup 0/F). The testing program developed by Burns and Roe, Inc. and Oak Ridge National Laboratory is formulated to identify the behavioral trends from the effects of elevated temperature on the mechanical properties of unconfined compressive strength, shear strength, reinforcing bar bond strength, sustained loading (creep) behavior, and the physical properties of thermal expansion, conductivity and diffusivity.
