This study investigated the fire-resistant characteristic of high strength concrete according to the change of the thickness and the adhesive method of fireproof plaster board and the results are summarized as followings. From the characteristic of fresh concrete, both slump flow and air content were appeared to satisfy each target range and the compressive strength appeared the range of high strength as 89.9 MPa from the characteristic of hardened concrete. From the characteristic of spalling, at all specimens of which the upper side finishing was not performed, the severe spalling that all covered concretes on 4 sides were felled off and internal reinforcing bars were exposed was occurred and spalling was appeared to occur even to the internal concrete. But, in case of specimen of which the upper side finishing was performed, spalling was not occurred. As the highest temperature of reinforcing part of each test after fire-resistant test, 19F1-MN-N showed 1036℃ and 19F1-MN-T showed 272℃. 19F1-ML-T that had grouted lightweight mortar appeared the most excellent capability as 116℃. As for mass loss rate after fire-resistant test, 19F1-MN-N appeared the most mass loss rate as 27 % but specimen of which the upper side was finished appeared the low mass loss rate as around 7 %. |
