Abstract:
A cement reinforcing fiber of the present invention is a cement reinforcing fiber made of a polyolefin fiber, wherein a fiber treating agent is adhered to a surface of the polyolefin fiber, and the fiber treating agent is a polyoxyethylene alkyl phosphoric ester salt. One preferred polyoxyethylene alkyl phosphoric ester salt is a compound represented by chemical formula (2) below. A cured cement of the present invention contains the above-described cement reinforcing fiber. In the chemical formula (2) above, R is an alkyl group with a carbon number of 2 to 20, A is an alkali metal element, and n is 1 to 20.
