Abstract

In this Study, FR-ECC(Fire Resistance Engineered Cementitious Composites) in which at same time it can improve the endurance and fire-resistance efficiency of a Structure was developed, and the experimental study such as thermal characteristic, Fire-resistance efficiency, and etc was performed for using FR-ECC as the repair materials for building and civil Structure. Moreover, it was evaluated about the field applicability of FR-ECC. As a result, FR-ECC is superior to the existence fire resistance repair mortar in strength and durability property. Also, FR-ECC was exposed to have the characteristic of being excellent than existence fire resistance mortar in the field applicability.
