Abstract: A concrete block includes a dry cast concrete body having opposite first and second sides, opposite first and second end faces extending between the first and second sides, and opposite first and second bearing faces extending between the first and second sides and the first and second end faces. Each of the first and second bearing faces defines an inset region sized to receive a key that will also fit into the inset region of a like block stacked thereon. The body has at least a pair of rod-receiving apertures extending completely therethrough between the first and second sides to permit attachment to a like block through the first and second sides with a rod extending through each of the apertures. The block can be tapered to form curved walls.

Abstract: A concrete block system is provided and allows for the use of a single type of non-integral connector to perform different functions in a mortarless structure, the system comprising a plurality of structural concrete blocks and a plurality of veneer units. The same connector can be used to connect veneer units to structural blocks, to retain the veneer units in different orientations; to create near vertical installations or a setback between stacked rows of structural blocks. In addition, the system provides a single structural block, which can be used for both straight portions or corners of a same structure. The structural block can also be used to create double-sided walls, with opposite lateral walls being configured to received/retain veneer units thereon.
