Abstract (en)
A building block comprises two opposite faces (2, 4), and two pairs of parallel sides (8, 6 and 10, 12). Outside flanges (26) extend along a first two sides (8, 12), defining channels (34) along the first sides between the faces and spaced apart therefrom. Central shoulders (22) extend along a second two sides and are spaced apart from the faces. Each of the shoulders (22) along each of the second sides has a lateral extent such that each shoulder (22) can fit closely within the channel (34) along an adjacent side of another such block and a height less than the depth of the channel along the adjacent side, to provide a passageway between the blocks.
