Fire safety is one of the important factors to be examined when applying ECC to actual concrete structures. The purpose of this study is to confirm whether the fire resistance of ECC satisfies the fire resistant requirements in order to use the fire protection material in concrete structures. Employed temperature curve are HC and RABT criterion, which are severe in various criterion of fire temperature in concrete structures. The test results show that ECC did not undergo any deterioration of fire resistance nor cause explosive spalling, which had been anticipated due to the presence of organic fibers. With comparison of current concrete and fire-resistance materials, the experimental results of ECC shows the better fire resistance performance than the other.

Reinforced concrete (RC) shield tunnel lining must be designed for fireproof performance because the lining is sometimes exposed to very high temperature due to traffic accidents. Both experimental and numerical studies are carried out to evaluate fire resistance performance of precast RC tunnel lining systems. In the experimental studies, six full-scale precast RC tunnel segments are exposed to fire in order to examine the influence of various parameters on the fire resistance performance of precast RC tunnel lining. We used the temperature curve of the RABT criteria, which are severe conditions of fire temperatures. The fire test showed that the explosive spalling was not observed by substituting concrete to PP fiber reinforced concrete. A transient heat flow analysis was carried out in consideration of the material properties that change with temperature, and the results showed good agreement with the test results.
