(57) The invention relates to a construction block (2) made of inert material, such as concrete, comprising two opposing  main surfaces (4, 6), an upper surface (8), a lower surface (10), and two opposing side surfaces (12, 14), the upper and lower surfaces (8, 10) as well as the side surfaces (12, 14), respectively, having complementary raised patterns capable of fitting together during a juxtaposition of a plurality of blocks. The raised pattern of the upper surface (8) comprises two tenons (16) extending parallel to and separated from the two main surfaces (4, 6), respectively, and the raised pattern of the lower surface (10) comprises two corresponding grooves (16‘) extending parallel to and separated from the two main surfaces (4, 6), respectively.
