An insulated masonry wall system comprised of special blocks of 24″×16″×8″ dimension filled with reclaimed rubber crumbs resulting in high R values to resist transmission of heat and cold. Insulation is blown and vibrated into the special concrete blocks as walls are developed. Construction of wall will be similar to standard masonry blocks. Facings attached to the blocks can be vinyl and wood siding, brick, stucco, textured acrylic finish, fiber-cement siding hardboard, photovoltaic siding, and wood shakes.

Embodiments relate to an enhanced method for building walls by primarily reducing the time for assembly. The design is for a molded multi-segment plastic composite construction block that interlocks horizontally, vertically and orthogonally with a clearance-fit, does not require mortar for structural integrity and is self-aligning. The blocks are molded out of natural-fiber reinforced thermoplastic composites with thermal expansion coefficient less than 0.0002 per degree Celsius and compression strength greater than 60 MPa.

A construction block unit includes a construction block and a lid. The construction block includes a bottom plate having a shape, a sidewall extending perpendicularly from the bottom plate at an outer edge of the bottom plate to form a container configured to receive and contain a weight, and fasteners coupled to a top edge of the sidewall opposite the bottom plate. The lid has a congruent shape to the shape such that the lid is fastenable to the top edge of the side wall via the fasteners to enclose the container. An interlocking portion of the construction block is shaped to receive a corresponding interlocking portion of a second construction block by vertically sliding the corresponding interlocking portion into the interlocking portion, interlocking the construction block and the second construction block to prevent separation by a horizontal force.

An insulated concrete block assembly includes a plurality of blocks is provided and each of the blocks is comprised of a mixture of 60.0 percent Portland cement, 30.0 percent expanded polystyrene foam and 10.0 percent lime. The blocks are stackable on each other to define an exterior wall of a building. A fluid insulation is pourable into each of the voids in each of the blocks when the blocks are stacked, and the fluid insulation is comprised of 70.0 percent polystyrene foam. 25.0 percent Portland cement and 5.0 percent lime. A tensioning cable is provided and a base of the tensioning cable is embedded into a foundation upon which the blocks are stacked. The tensioning cable is tensioned to a pre-determined tension load when the tensioning cable is routed through the voids of the blocks that are stacked.

A masonry unit may include a main portion having end surfaces, a primary side surface, and a secondary side surface, and an auxiliary portion positioned adjacent to the main portion and defining an auxiliary void. The auxiliary portion may be connected to the main portion at the secondary side surface. The auxiliary portion may include an auxiliary wall being spaced from the secondary side surface to define the auxiliary void therebetween, and at least one bridging web extending across the auxiliary void and connecting the auxiliary wall to the main portion, the at least one bridging web being inset from the opposite ends of the unit, the at least one bridging web being integrally formed with the main portion and the auxiliary wall. The auxiliary void may extend from one end to another end of the unit and may extend from the top to the bottom of the unit.

A massive block preferably made of compressed earth is described as well as a method to build walls utilizing the massive blocks. By combining wooden frame construction and massive wall construction with bricks or other massive block elements, a wall can be built with the advantages of both. A wooden stud frame is erected, the electricity and other utilities are placed through the frame and then the frame is covered up on both sides with large massive blocks of a specific design that interlock with both the frame and each other. The cavities in between the blocks can then be filled up with a filler such as sand to create additional thermal mass and improve the sound insulation properties of the wall. A second embodiment of the wall utilizes an extra layer of blocks with grooves to accommodate a radiant heating system and insulation material.
