Abstract
The present invention discloses an arched steel fiber for reinforcement of a cement-based material, of which a main body is arched in a length direction and opposite ends of the main body are curved such that the steel fiber has a higher pullout resistance strength compared to a conventional steel fiber, thereby improving mechanical performance such as a tensile strength, a flexural strength, an energy absorption capability, and the like of a cement compound. In addition, compared to a conventional art, a mixing amount of steel fiber to performance can be reduced so that an added economic value in terms of consumable cost can be created.
