To provide a fiber-reinforced cement composition and a concrete structure in which the dispersibility of a fiber is enhanced, and which exhibit good workability and have high uniformity, high durability and high toughness; and to provide a method for producing a concrete base material.
The fiber-reinforced cement composition is used for repairing concrete and contains a cement-based inorganic material, a synthetic fiber and/or a carbon fiber, a pozzolan material, a thickener and a water reducing agent. In the fiber reinforced cement composition, the synthetic fiber and/or the carbon fiber are contained in an amount of ≥0.5 and ≤3.5 vol.% to the total volume of the cement-based inorganic material, the pozzolan material, the thickener and the water reducing agent.
