A concrete block is provided having half dovetail sections at opposite ends of the block arranged so that when placed together the dovetailed sections on adjoining blocks form a full dovetailed section which is just large enough to be received within a dovetail groove in the central portion of an adjacent identical block. The concrete blocks are provided with upper and lower longitudinal grooves for longitudinal members having the same exterior shape. In one form of the invention one side of the block may be made into a plant receptacle by providing a hollowed out section oriented upwardly. Insulating concrete blocks may also be combined with blocks formed of structural concrete to provide an interlocked wall having a portion of the wall made from insulated concrete material and another portion of the wall made from structural concrete material.

[ I claim:] [1.] An assembly formed of a plurality of identically constructed, interengaged structural blocks whereina. each structural block comprises:(i) an insulating concrete composition,(ii) a planar face having four corners, with lateral-side extensions at opposite ends of the structural block each having a half dovetail configuration thereby defining a pair of first and second surfaces, the second surfaces having a generally planar profile and constituting an abutment edge of each side extension for abutment with adjacently located, interengaged structural blocks,(iii) a central depression extending between the pair of first surfaces and defining between such half dovetail configuration extensions a dovetail groove having a configuration and dimensions adapted to receive and interlock with two oppositely disposed adjacent half dovetail configuration extensions from opposite structural blocks,(iv) intersecting parallel, horizontal and parallel, vertical grooves extending circumferentially around the block and located beneath the face of the block where the horizontal grooves extend within the first surfaces of the structural block and the vertical grooves extend within the second surfaces of the structural block,b. the abutment edges of a first structural block each being paired with an abutment edge of an adjacent structural block of the same construction and wherein such abutting pairs of half dovetail configuration side extensions are positioned within the central depressions of adjacent structural blocks forming a first course of blocks, at least second course of blocks formed as said first course of blocks, and parallel horizontal and parallel vertical grooves are opposed when each course of structural blocks is formed and consecutively arranged courses of structural blocks are positioned thereupon forming horizontal and vertical chambers between the structural blocks themselves and the courses of structural blocks forming an interlocking double structural block wall arrangement with interior elongated chambers, andc. at least portions of the chambers between the structural blocks themselves and the courses of structural blocks are occupied by longitudinally extending lintels which serve to directly align and interengage the structural blocks with adjacently located abutting structural blocks and with courses of structural blocks comprising the wall arrangement.
