Abstract
A wall construction system including plurality of interlocking concrete blocks. The interlocking blocks include one or more stretcher blocks, corner blocks, and half blocks. The blocks include top and end shear lugs and bottom and end grooves. The bottom grooves accommodate the top shear lugs of blocks in a lower course of stacked blocks. Corner blocks provide a means for creating a corner and turning the direction of a course of blocks by 90 degrees. The interlocking features of the blocks enable dry-stacking in successive courses to construct a wall or multi-wall structure. When stacked end to end in successive rows, the top and end shear lugs of each interlocking block engage complimentary grooves in the underlying, overlying, and adjacent blocks thereby enabling the blocks to rapidly self-align vertically and lock together as they are stacked. The resulting dry-stacked structure exhibits a high lateral resistance to overpressures or transverse loads.
