Abstract:Fiber reinforced concrete has been used for shotcrete concrete structures, floors and pavements structures and precast applications. Recently, fiber reinforced concrete has been applied for repairing and strengthening the bridge structures which are deteriorated by heavy traffic load, corrosion and freezing and thawing action. One of the most popular repair/strengthening methods is overlay techniques to increase the slab thickness. In this case, the fiber reinforced overlay structures are required to be high fracture toughness in compression as well as in flexure. However, the compressive toughness of fiber reinforced concrete has not been sufficiently studied, although there are many reports about the flexural toughness. In this paper, fracture toughness of fiber reinforced concrete is studied in compression as well as in flexure. Four different types of steel fiber and two types of polyvinyl alcohol (PVA) fiber were used with two types of fiber together or as single types of fiber. Hybrid effects of fracture toughness in compression as well as in flexure were investigated by mixing the steel and PVA fiber. The simple effects of fiber type, fiber content, fiber geometry, on fracture toughness were also investigated with using steel fiber and PVA fiber by themselves.
