Document Type and Number:
Japanese Patent JP6745227
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a cement material reinforcing fiber excellent in durability in a reinforcing effect, and capable of effectively reinforcing a cement material by using a plant-derived lignocellulose fiber; a fiber-mixed cement material using the cement material reinforcing fibers; and a method for producing the fiber-reinforced cement material using the cement material-reinforcing fibers.SOLUTION: A cement material reinforcing fiber of the present invention is made up of a lignocellulose fiber to which a fiber surface coating agent is attached, the fiber surface coating agent being selected from the group consisting of a resin, a cellulose nanofiber, and a lignocellulose nanofiber. A fiber mixed cement material of the present invention comprises the cement material reinforcing fibers and cement of the present invention. A method for producing a fiber reinforced cement material of this invention includes a kneading step of mixing the cement material reinforcing fibers or the cement material reinforcing fibers obtained through a method of this invention, the cement, and water, wherein the method does not include a step of conducting dehydration after the kneading step.SELECTED DRAWING: None
