A method for producing a composite insulating mineral construction element includes filling the cavity of a construction element including at least one cavity delimited by at least one inner wall at least partially having a water absorption rate of more than 5 g/(m.sup.2.Math.s) at 10 minutes according to standard NF EN 772-11 of August 2011 with a foamed cement slurry including a cement being an hydraulic binder including a proportion of at least 50% by weight of calcium oxide CaO and silicone dioxide SiO.sub.2, a metal salt selected from an aluminium, magnesium or iron salt and mixtures thereof, and a cellulose ether; and leaving the foamed cement slurry to set within the cavity resulting in the formation of a mineral foam, wherein the foamed cement slurry includes from 0.01 to 0.2% by weight of cellulose ether, relative to the weight of cement.

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.

The disclosed technology includes a polyurethane foam block including a base having a plurality of recesses and a top surface having a plurality of connective components protruding outward from the top surface where each connective component of the plurality of connective components can align with a recess of the plurality of recesses. The polyurethane foam block can include a plurality of walls extending upward from the base and defining an interior. The polyurethane foam block can include a plurality of partitions extending from the base to the top surface to divide the block into a plurality of cavities, each cavity traversing a height of the block.

An insulated block includes two sides and a self-adhering foam core joined to the two sides during the curing of the foam core. The foam core includes protrusions and recessions to facilitate joining of each insulated block with another insulated block. The insulated block is configured to be joined to other insulated blocks to create a structure or foundation which does not require mortar.

A building element formed as a sandwich of outer panels (22) made from high strength thin-walled geopolymer concrete (GPC) and a high insulation core material (21) of high-density polystyrene providing thermal efficiency. The outer panels are offset from the core material to provide an edge interconnecting mechanism with adjacent elements and, furthermore, the core material (21) includes surface features/profile (26) that abut/mate with corresponding features in the adjacent core material. A building system utilising the element in block or panel form provides simple and fast construction, without the need of skilled labour. Furthermore, since the insulating core provides a locking and locating interconnection means between the elements this effectively results in a zero-loss system due to bridging. When combined with a compressive vertical tie bar system the outcome is a wall construction of exceptional strength and accuracy.

A concrete building block for masonry block walls is formed with first, second and third spaced parallel rectangular face shells, where the second face shell is intermediate the first and third face shells. First and second vertical end cross webs connect the first and second face shells and first and second spaced intermediate vertical cross webs connect the second and third face shells. Insulating inserts include end protrusions extending outwardly at the top edge thereof to fit into notches of the cross webs and include cutouts to accommodate mortar crumbs. The inserts further include longitudinal notches along the entire bottom edges and longitudinal notches along the entire top edges wherein said longitudinal notches along a bottom edge are dimensioned to mate with longitudinal notches along a top edge of neighboring ones of the insulating inserts creating an overlap that serves to (i) insulate against temperature transfer and (ii) provide a sound barrier.
