Mix formulation for 3D printing of structures is described, including a composition of an aluminosilicate source and an activator. Also described is a method that includes combining a composition having an aluminosilicate source and an activator with aggregate to yield a mixture, extruding a first quantity of the mixture through a nozzle to form a first layer of the mixture, extruding a second quantity of the mixture through the nozzle to form a second layer of the mixture substantially on the first layer, and curing the first layer and the second layer to yield a structure printed using a 3D printer.

Provided is a method for drying a wet-gel blanket which can have an excellent heat insulation performance by minimizing shrinkage of a gel network structure that occurs during drying, and has excellent drying efficiency versus time, and a method for producing an aerogel blanket using same.

Devices, systems, and methods of the present disclosure are generally directed to building material including particles of a polymer in an irradiated form, a cement including calcium oxide, and at least one additive including silicon dioxide. In cement paste formed from a mixture of these components, the polymer in the irradiated form may decrease porosity as compared to porosity of cement paste formed without the polymer, and a combination of the silicon dioxide and the calcium oxide may form high-density phases in the cement paste. With these characteristics, such cement paste may exhibit at least the same compressive strength as cement paste formed from the cement by itself. Thus, in certain instances, the particles of the polymer may displace a portion of the cement in a manner that maintains compressive strength while facilitating reduction of greenhouse gas emissions associated with cement paste formation.

Drill cuttings, initially cleaned to remove a majority of drilling fluids therefrom, but which have residual organic species, including hydrocarbons, therein are used in clean technologies to make a wide variety of ceramic and concrete products, such as tiles, slabs, blocks, bricks, pavers, decorative edgings, planters, modular barriers, embankments, medians, dividers, precast products and the like for a variety of commercial sectors. In the case of the concrete products, the organic species in the drill cuttings, including hydrocarbons, are first minimized or degraded in the drill cuttings using an oxidative process, such as photocatalytic oxidation, use of an oxidant or combinations thereof, prior to mixing the drill cuttings with cement and water, to form various concrete products. The products produced have acceptable compressive strengths and minimize or eliminate any leaching of the drill cutting contaminants therefrom. In the case of the ceramic and advanced ceramic products, the hydrocarbons and other contaminants are melted during the process of firing the ceramic products in the kiln. The kiln temperature is carefully controlled to minimize safety issues, which would otherwise be associated with the presence of at least the hydrocarbons in the products.
