Abstract:
A concrete block includes first, second, third, fourth, fifth, and sixth planar faces. The first and second faces are generally parallel, and the distance between the first and second faces define a thickness of the first block; the third and fourth faces are parallel to each other and perpendicular to the first and second faces; the fifth face is perpendicular to the first, second, third, and fourth faces; the sixth face: extends perpendicular to the third face; extends toward the fourth face and ends at a non-planar remainder section; is parallel to the fifth face; is contained in a plane that intersects a plane containing the third face; and a distance from the intersection to the remainder section is at least as long as the thickness of the first block; and the remainder section extends between the sixth face and the fourth face and has a shape such that when a second block of the same construction as the first block has its remainder section engaged against the remainder section of first block, the remainder sections of the first and second blocks mate.
