This experiment adds basalt fiber at 0, 0.3, and 0.5% of binder volume to composite concrete and evaluates fresh, strength, durability, and elevated-temperature response from 200-800°C for heat-exposed construction.
Key findings
- The 0.3% mix reached 790 mm flow; the 0.5% CCM8 mix reached 63.90 MPa compressive strength versus 52.76 MPa control, with 1.10% water absorption and improved sorptivity. Temperature-specific retained-strength values are absent from the abstract.
Why this matters globally
Noncorrosive basalt fiber may improve concrete toughness and durability, but fire-resistant use requires standardized residual strength, spalling, and thermal-gradient evidence, not only 28-day properties.
Thai researcher contribution
Walailak and Burapha researchers contributed to an international collaboration on fiber-reinforced concrete under elevated temperatures.
Limitations to consider
Replication, statistics, heating/cooling protocol, dwell time, and key residual values are not stated. High flow may involve segregation, and specimen tests do not establish structural-member, bond, or real-fire performance.
