Recently, the evaluation of fire resistance performance is necessary to use the ultra high strength concrete on the high-rise building. On this study, the loading and heating test is performed for 200MPa ultra high strength concrete using nylon fiber at General Building Research Corporation of Japan. Several tests are performed for evaluation of fire-resistance performance: Tests for concrete characteristics strength properties, pre-test for fire resistance, loading and heating test followed by ISO-834 heating curve on the real-size specimen. Test for residual strength of the column structure after fire-resistance test will be performed.

Worldwide, Certification systems for standard of material and quality of product exist very variously. Korean industrial Standard (KS) is most representatively certification systems in Korea. But labolatory of korea uses often ASTM, RILEM and JIS and these standards do not get into unionization. so, Granted that experiment is same, result still can different. Therefore, this research measured chloride amount of hardened concrete using identical material and wished to improve accuracy of chloride estimation as that comparison evaluate to each examination.

As a result of measuring the compressive strength and semi-adiabatic temperature rise of the mixed mortar, it was confirmed that the mortar mixed with the hydration heat reducing material is effective. On the other hand, the compressive strength showed similar strength to that of moderate heat Portland cement until the age 7 days, but after that, the tendency of the strength development to be delayed was confirmed.
