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.
Claims8
A method for preparing a carbon fiber-reinforced cement material containing a carbon fiber as a reinforcing material, which is characterized by comprising the steps of;
- subjecting the carbon fiber to a water replacement treatment wherein an amount of the gas captured by the fiber is reduced by replacing the gas with water;
- and uniformly incorporating the treated carbon fiber into a cement matrix.
