ARCHED STEEL FIBERS FOR REINFORCING CEMENT-BASED MATERIAL

摘要

The present invention has higher pullout resistance strength than prior art by longitudinally arching the main body of arched steel fibers for reinforcing a cement-based material and bending both ends thereof and thus can ultimately improve the mechanical properties, such as tensile strength, flexural strength, and energy absorption capacity, of a cement composite. In addition, the present invention can reduce the content of the steel fibers against performance in comparison with the prior art and thus even obtain technical effects including the creation of economic value added in terms of the costs of materials consumed.
