[미발표]내화모르타르의 물리 및 내열 특성에 관한 실험적 연구

Recently, the underground traffic structures in city have increased. Fires caused by collision with the vehicle securing the safety of underground structures is needed. Fires in tunnels and underground structures characteristic of a closed space, so many damages of human life and economic losses are underground structures. In this study, Fire resistant mortar made with ployamid fiber and a variety of lightweight aggregates(vermiculite, pearlite). physical and fire resistant are evaluated through experiment. Also, The actual tunnel structures, numerical analysis by finite element method was carried out. and anti-spalling and fire resistant of structures to improve compliance were evaluated.
