Abstract
It is a trend to increase safekeeping properties in financial company as the world economy situation has been globalized and advanced. The development of a securable vault door resisting to malicious trespass is needed. Therefore, this study focuses on developing high performance concrete placed at the inside of the vault door, and all materials used in this study is easy to obtain in domestic considering economic competitiveness. The compressive strength over 170 MPa was targeted, and structurally strengthening was also planned in order to resist to over $3,000^{\circ}C$ heating by torch and extreme impact loading by hammer drilling machine. Several types of fibers and reinforcing structures were used in order to resist those external heating and loading. This purpose was required to satisfy UL 608 standard of a vault door. Consequently, the result from this study is expected to be applied to construction field of major facilities, which should guarantee the safety from an external attack such as terror.
