To examine how basalt fiber reinforced recycled aggregate concrete (BFRRC) deforms after being exposed to high temperatures, the deformation characteristics tests were conducted on 81 standard prismatic specimens with replacement ratios of recycled coarse aggregate (RCA) (0%, 50%, and 100%), basalt fiber (BF) dosage (0 kg/m³, 2 kg/m³, and 4 kg/m³), and temperature (25 °C, 300 °C, and 600 °C) as the variation parameters. The variation factors on deformation characteristics such as elastic modulus and Poisson's ratio of BFRRC were discussed. The analytical expressions of the elastic modulus of BFRRC with different variation parameters after high-temperature treatment were proposed. Results show that the elastic modulus gradually decreases with the increasing of replacement ratio and temperature, and gradually increases with the increasing of BF dosage. The increase of Poisson's ratio is primarily concentrated between 300 °C and 600 °C, and the 100% replacement ratio of recycled aggregate has the greatest influence on the Poisson's ratio. The variation parameters on Poisson's ratio are opposite to that of the elastic modulus. The conclusions obtained in this study provide a significant reference for design and application of BFRRC after high temperature. [ABSTRACT FROM AUTHOR] |
