DEVELOPMENT OF STEEL-FIBER REINFORCED HIGH FLUIDITY CONCRETE SEGMENT AND APPLICATION TO CONSTRUCTION

摘要

SFRC segments are made of short steel fibers (Photograph 1) and self-compacting highly flowable concrete (Photograph 2). SFRC segments make it possible to reduce main reinforcement and eliminate transverse reinforcement and hoop reinforcement. Figure 2 shows the structural outlines of SFRC segment and conventional RC segment. SFRC segments have the following characteristics.
