Steel fiber was introduced to Japan about 40 years ago. Characteristics of steel fiber are substantially affected by the manufacturing method. Therefore, first of all, manufacturing methods of steel fibers are described. The next place, characteristics of steel fiber reinforced concrete (SFRC) are shortly reviewed. It is well known that concrete or mortar is one of the fragile materials that possess low tensile strength and relatively high compressive strength. The addition of steel fibers randomly distributed in the matrix, substantially improves their mechanical performance such as residual strength in compression, strength/toughness (energy required up to failure) in bending, impact strength, fatigue strength and also wear resistance. In the past 40 years, SFRC had been gaining various application fields. In the final part of this report, main application fields of SFRC are picked up and shortly explained. For example, SFRC was used for tunnel support, dam site, river facilities, road pavement and floor in building. In most application fields, SFRC has obtained excellent reputations by virtue of its durability under severe physical and environmental conditions.Many researches concerning steel fiber and SFRC are now undergoing and SFRC is still gaining new application fields.
