Abstract: A dry-cast concrete block for use in a structure comprising a plurality of concrete blocks. The dry-cast concrete block comprises three convex sides and three concave sides alternating with the three convex sides. The dry-cast concrete block also comprises a surface located between the three convex sides and the three concave sides and comprising at least one portion having a cast texture with a natural stone appearance. Each of the three convex sides is adapted to register with either one of three concave sides of an adjacent one of the concrete blocks to enable positioning of the dry-cast concrete block in different positions relative to the adjacent one of the concrete blocks.

Abstract: A dry-cast concrete block system for use in a structure. The dry-cast concrete block system comprises a support block comprising a first coupling part and a face block comprising a second coupling part. The first coupling part and the second coupling part enable the face block to be coupled to the support block. The face block comprises a surface adapted to be exposed when the face block is coupled to the support block and the dry-cast concrete block system is positioned in the structure. In one embodiment, at least a portion of the surface has a cast texture with a natural stone appearance. In one embodiment, the structure is a wall and the concrete block system is a wall block system. For example, the wall may be a retaining wall and the wall block system may be a retaining wall block system. In another embodiment, the structure is a column and the concrete block system is a column block system. In yet another embodiment, the structure is steps and the concrete block system is a steps block system.
