A composite foam and concrete wall includes a foam layer having a top surface, a bottom surface, a left wall surface and a right wall surface wherein the foam layer comprises at least two foam panels that define a seam that is substantially parallel to the top surface and the bottom surface. A concrete layer is secured to a surface of the foam layer.

A photovoltaic power source includes a receptacle to receive a photofuel including a liquid, and one or more photovoltaic cells positioned within the receptacle to receive light emitted from the photofuel when the photofuel is in the receptacle. The photovoltaic power source also includes power circuitry coupled to the one or more photovoltaic cells to receive a photocurrent generated by the one or more photovoltaic cells when the one or more photovoltaic cells receive the light emitted from the photofuel. In response to the photocurrent, the power circuitry is coupled to output electricity.

An ultrastable cementitious material with nano-molecular veneer makes a cementitious material by blending 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide based on a final total weight of the cementitious material, with 14 wt % to 18 wt % of a magnesium chloride dissolved in water and reacting to form a liquid suspension, mixing from 2 to 10 minutes, adding a phosphorus-containing material, and allowing the liquid suspension to react into an amorphous phase cementitious material, wherein a portion of the amorphous phase cementitious material grows a plurality of crystals. The plurality of crystals are encapsulated by the amorphous phase cementitious material forming a nano-molecular veneer. A process to make the ultrastable cementitious material. A tile backer board incorporating the ultrastable cementitious material and a process for making the tile backer board.

Disclosed are a wall construction system with drywall composite columns and a method for constructing walls using thin sheet steel sections in concrete composite construction for erecting story-high walls with at least one-sided planking with building boards, in particular for residential buildings. Structural loads of solid ceilings and facade walls are absorbed via the composite columns arranged in a modular grid within the wall plane. The joining of the composite columns takes place at the column head over a concrete beam on which the ceiling rests. In-filling wall or facade elements may be arranged between the composite columns. The composite columns include a concrete composite column with a sheet metal reinforcement and a spatially offset thin-walled sheet steel section for mounting drywall thereto even after the metal reinforcement has been filled with concrete. The sheet metal reinforcement and the thin-walled sheet steel section may have different material qualities and thicknesses.

A wall construction includes a number of spaced apart, upright channel-shaped studs having open upper ends, and a number of panels forming an exterior wall. The panels have tie members that extend into the studs. An elongate support member is attached to the studs adjacent to the upper ends of the studs. The support member does not block access to the upper ends of the studs so that the studs can be filled with concrete with the support member remaining in place attached to the studs.
