PROBLEM TO BE SOLVED: To make force transmitted from a steel cord strand to a cement member large, to increase the number of cracks by dispersing external force, to reduce the widths of the cracks, and to reduce the widths of the cracks of the cement member. SOLUTION: A steel cord panel 50a including steel cord strands 5 arranged in parallel along the insides of both end surfaces of a cement wall material 1 is arranged and embedded in the cement wall material 1. A steel cord panel 50b including the steel cord strands 5 arranged in parallel along the insides of the upper and lower end surfaces of the cement wall material 1 is arranged and embedded in the cement wall material 1. Since the steel cord strands 5 are arranged near the surface of the cement wall material 1, the widths of the cracks formed in the surface are reduced. COPYRIGHT: (C)2006,JPO&NCIPI
