Post-heating evaluation of residual compressive and tensile mechanical properties of basalt fiber reinforced recycled aggregate concrete

Key Points

• Residual compressive and tensile strengths were assessed after heating, indicating material performance under thermal conditions.
• The compressive strength remained relatively stable after heating, measuring up to 40 MPa in specific conditions.
• Assessment involved testing various concrete samples with different basalt fiber percentages to evaluate mechanical properties.
• Findings highlight the potential of using basalt fiber reinforced concrete in applications exposed to high temperatures.
