Abstract (en)
[origin: WO2007128082A1] A building block having a body with three sets of opposing outer sides defining thereby a generally rectangular outer shape, the body having at least one passageway having an upper open end at a top of the block and an open lower end at a bottom of the block. An inner part of the block is comprised of a first material, and a second different material surrounds the inner part providing thereby an at least substantially continuous outer surface of said second material. A one side of a one of the sets of opposing sides having at least one protrusion extending outwardly from a planar surface of the side, and at least one cavity in the further opposed side of the same set of opposed sides in a position and of a size to receive and effect an alignment of a further block having the same shape and size of this first defined block, by receiving a or the protrusions into the cavity or cavities.
