PROBLEM TO BE SOLVED: To provide a concrete block which is formed of a recycled waste tire and has such a good appearance that recycling of the waste tire cannot be recognized from the outward appearance, and to provide a method for using the concrete block which can construct a slope surface and a retaining wall being excellent in design. SOLUTION: The waste tire 1 is cut and divided along a first virtual plane 3a inclusive of an axis 2, and concrete is placed in a space enclosed by second and third virtual planes 3c, 3d which make contact with side wall portions 11, 12, respectively, and are in parallel with a tire equatorial plane 4a, and curved surfaces of a tire tread portion 13 of the divided waste tire 10, to thereby form the concrete block. To use the concrete block thus formed, a finish surface 31 is faced to a wall front surface B to be constructed, and the side wall portions 11, 12 are faced upward and downward, followed by aligning the concrete blocks such that the tire tread portions 13 are abutted on each other. Then, the thus aligned blocks are vertically stacked. COPYRIGHT: (C)2003,JPO
