| Research Abstract |
The researcher examined the relationship between spalling behavior and weight loss for ultrahigh-strength fiber-reinforced concrete (UFC) containing different kinds of short fibers (jute, PP,WSPVA) in high-temperature environments at 400, 600 and 800°C. The explosive spalling that occurredunder these conditions caused severe damage to the control specimen without fiber reinforcement but only slight damage to the jute specimen. It was therefore inferred that adding 0.19% by volume of natural jute fibers (length: 12 mm) to UFC is effective in the preventionof spalling-related damage.
