Mortarless interlocking concrete block system

Abstract

A mortarless interlocking concrete masonry unit system includes concrete blocks comprising field blocks, corner blocks, end blocks, and intersecting blocks. Each block includes an interlocking geometry with protruding portions and recess portions configured to engage with adjacent blocks through approximately fifty percent overlap connections. The interlocking geometry enables mechanical bonding in longitudinal, lateral, vertical, and transverse orientations without requiring mortar joints. The system creates structural assemblies through self-aligning connections that resist shear forces while eliminating the need for skilled masonry labor. Central cavities in each block accommodate utility installations and reinforcement materials. The corner blocks provide ninety-degree connections, end blocks enable wall terminations with finished surfaces, and intersecting blocks enable perpendicular wall additions at any location. The lightweight concrete blocks are approximately fifty percent lighter than conventional masonry units while maintaining equivalent structural performance for walls, partitions, foundations, and load-bearing structures.

         10 . A concrete block comprising:
 a block body;   an interlocking geometry formed on the block body, the interlocking geometry comprising one or more protruding portions and one or more recess portions, wherein at least one protruding portion of the one or more protruding portions is configured to engage with at least one recess portion of an adjacent block; and   wherein the interlocking geometry is configured to permit connection in at least one of longitudinal, lateral, vertical, or transverse orientations.   
     
     
         11 . The block of  claim 10 , wherein the engagement between at least one protruding portion and at least one recess portion covers approximately fifty percent of a block face. 
     
     
         12 . The block of  claim 10 , wherein the block is a field block having interlocking geometries disposed on opposing faces of the block body. 
     
     
         13 . The block of  claim 10 , wherein the block is a corner block having interlocking geometries disposed on perpendicular faces of the block body. 
     
     
         14 . The block of  claim 10 , wherein the block is an intersecting block configured to engage with at least three adjacent blocks. 
     
     
         15 . The block of  claim 10 , wherein the block is an end block having one finished exterior surface and one interlocking surface. 
     
     
         16 . The block of  claim 10 , wherein the block body further comprises a central cavity extending longitudinally through the block, wherein the central cavity is configured to receive pipes, electrical conduits, or structural reinforcement elements. 
     
     
         17 . A method of constructing a mortarless wall, comprising:
 providing a plurality of concrete blocks, each of the plurality of concrete blocks comprising an interlocking geometry comprising one or more protruding portions and one or more recess portions, wherein at least one protruding portion is configured to engage with at least one recess portion of an adjacent block;   aligning a first block of the plurality of concrete blocks with a second block of the plurality of concrete blocks such that at least one protruding portion of the first block engages with at least one recess portion of the second block;   repeating the alignment with additional blocks including at least a corner block, an end block, and an intersecting block; and   forming a structural wall assembly without a use of mortar.
