Abstract
A plurality of solid core concrete blocks used in forming a retaining wall. The retaining wall can be used in building construction, road construction, landscaping, hillside erosion control, gardens, and like applications. Also, the retaining wall can be a straight wall, an angled wall or a curved wall depending on the application. Each of the blocks includes a vertical front face and rear face, a horizontal top and bottom and a vertical first side and second side. The first side includes a first ear and two sides of an angular first notch next to the first ear. One side of the first notch is parallel to a length of the front and rear faces and forms a side of the first ear. A second side of the first notch is disposed inwardly into the block and at an angle of 10 to 45 degrees from a horizontal line perpendicular to a length of the front and rear faces. When the first ear is broken off, a length of the second side of the first notch is extended for engaging a side of another block having a second ear broken off. In this manner, the retaining wall can be angled or curved during the wall construction.
