FIBER FOR REINFORCING CONCRETE AND CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a fiber for reinforcing concrete which prevents lowering of a bonding force between the fiber and concrete by forming unevenness on the surface of a covering material itself, and to provide a concrete structure with which the fiber for reinforcement is mixed.SOLUTION: There is provided a fiber for reinforcing concrete which is formed of a core material 1 formed of an inorganic fiber that is resistant to ultraviolet rays, and a covering material 2 covering the core material 1 and formed of an organic resin that is resistant to alkaline, where unevenness 7 is formed on the surface of the covering material 2 itself.SELECTED DRAWING: Figure 1
