Abstract
A method for preparing a carbon fiber-reinforced cement material is here disclosed which comprises the step of using, as a reinforcing material, a carbon fiber from which a gas has been removed by replacing the gas captured in the fiber with water. This method permits providing the carbon fiber-reinforced cement material having a large reinforcing effect by the fiber.
