Characteristics of Recycled Reinforced Concrete at High Temperatures

摘要

This study investigates the behavior of reinforced concrete and recycled fibre reinforced concrete influenced to temperatures of $200^{circ}mathrm{C}-500^{circ}mathrm{C}$, on two types of concrete such as recycled concrete, recycled fibre concrete. The experiment was conducted at the Structural Engineering laboratory at Ho Chi Minh City University of Technical Education. The characteristics, those are the failure, compressive strength, cracking were analyzed. Based on that, compressive strength of recycled fibre concrete has clearly changed in comparison with recycled concrete when subjected to temperatures of $200^{circ}mathrm{C}-500^{circ}mathrm{C}$. On the other hand, failure mechanism and shape of cracking are to-tally difference between two types of specimens.
