Set of concrete building blocks for constructing a dry wall

A set of interlocking concrete blocks for construction of a mortarless wall, comprising:

• frontal blocks (1), anchoring blocks (2) for effecting an anchoring of said frontal blocks (1) in an earth substrate, and connecting blocks (3) for effecting a close connection of opposed said frontal blocks (1);
• each frontal block (1) having a structured front side (4) and on its rear side at least one frontal block dovetail projection (5) relative to a top view, said frontal block (1) further comprising a first frontal block (1) having a first width (B) forming a base block, said frontal block (1) having a second frontal block (1) having a second width (1.5 B) about one and one-half times said first width (B) of said base block;
• said second frontal block dovetail projection (5) about one and one-half times wider than a first frontal block dovetail projection displaced asymmetrically to one side of said second frontal block (1) and said frontal block (1) having a third frontal block (1) having a third width (2 B) about two times said first width (B) of said base block;
• each said anchoring block (2) in said top view having a rectangular cross section (6) with anchoring block dovetail projections (7) integrally formed on each longitudinal side;
• each said connecting block (3) comprising two dovetail halves (8) formed together at a narrow side of each said dovetail halve (8);
• said front block dovetail projections (5), said anchoring block dovetail projections (7) and said dovetail halves (8) each having same dimensions.
