PROBLEM TO BE SOLVED: To provide a crack inhibiting reinforcing material surely resisting to a tensile stress causing cracks, capable of inhibiting the occurrence itself of cracks, having various advantages such as facilitating fastening to a steel bar, and installing concrete, and being inexpensive, and capable of greatly contributing to hardness enhancement of concrete. ! SOLUTION: A reinforcing material for inhibiting cracks is buried in a position near the surface of concrete along the surface, and uses as the material a steel thin band plate 2 whose longitudinal dimension is formed longer than a width dimension. There are formed on the steel thin band plate 2 by a regular pattern of at least one row, a large number of holes 3,3... which respectively are a polygon more than a hexagon, a circle or an ellipse, and have a size equal to or more than the maximum diameter of a mixed coarse aggregate. For instance, the holes 3, 3... are a plurality of rows and can be a model of a plurality of rows formed in a |
