A masonry wall system is disclosed incorporating a plurality of courses of masonry blocks, each block has vertical and horizontal interlocking structures with mating surfaces (11,15,16,17). The main block, has a stabilizing slot. Metal reinforcement tendons are inserted into these stabilizing holes (14) at predetermined intervals and connected to the wall at the top and bottom. Corner blocks (26) are employed to connect the walls at right angles and are used in alternating configurations to staggered the vertical joints from course to course. This is also done with the main blocks. The predetermined tolerances between the masonry components and the reenforcing tendons permit the wall to have a fluid property. Forces such as settling, hydrostatic pressure and seismic disturbances are then automatically absorbed and systematically distributed across the entire wall. When all of the masonry components reach the end of their tolerance, the wall locks up as a solid interconnected mass. The force is then passed on to the stabilizing tendons which now act to stabilize the wall against further movement. The movement of the wall can be adjusted after assembly of this wall by applying increased tension to the tendons.

Non-masonry building block components, including a standard hollow-bodied block component with horizontal and vertical locking capabilities which removes the need for bonding material such as glue, mortar or other adhesives.

Typically, use of the non-masonry building components would allow for constructing permanent or temporary structures having vertical and horizontal channels in which to allow plumbing or electrical conduit. The incorporation of materials, such as sand or similar substance, would form a bullet-resistant barrier for use in military operations. Additionally, structures formed from the block components could easily be assembled or disassembled on site without the need for skilled labor, specialized tools, demolition and clean up.
