The use of steel fiber for reinforcement has been attracted a great attention from academic and industrial parties. Various applications of this type have been using in pavements, segments, shotcrete, and drainage pipes etc. This steel fiber reinforcement has shown excellent performances in crack control and load distribution due to its 3D equally distributed location. This paper presents a series of tests and analysis for different types of steel fiber in concrete samples and beams. The comparison of experimental tests of conventional and steel fiber reinforced structures are carried out. The tests show positive results and possible applications to construction structures in Vietnam where many cracks and failures of these types of conventional structures have been reported.
