Nowadays, it is a requirement to use high strength concrete for skyscrapers. Therefore safety research for high strength concrete is necessary. A fire outbreak in a reinforcement concrete structure looses the organism by the different contraction and expansion of hardened cement pastes and aggregate, and causes crack by thermal stress, leading to the deterioration of the durability.
In this study, normal and high strength mortar were exposed to a high temperature environment. And than fundamental data for the character change of concrete heated highly were resented by measuring compressive strength of concrete with PP fiber and vinylon fiber, before and after heating.
As the result, it is proven that adding PP fiber and vinylon fiber in high strength concrete for prevents deterioration of durability by fire.
