Embodiments of the disclosure provide a reinforced composite material including a composite material forming a geometric body, and a reinforcement member disposed in the composite material. In some embodiments, the reinforcement member includes (i) at least one elongate metal wire extending at least partially through the composite material, and (ii) at least one barb that extends from the elongate metal wire in a transverse direction to the elongate metal wire.

A catalytic composition is built up from a ceramic material including a catalytic material and a first inorganic binder and a second inorganic binder and a catalytic structure made thereof. Preferably, the structure is made by a colloidal ceramic shaping technique. The structure is usable for catalytic or ion exchange applications as well. It is demonstrated that the catalytic structures have excellent mechanical, physicochemical and catalytic properties.

A 3D printable clay-based mortar cementitious ink includes a blend of commercially available Type I/II Portland cement, and a fine and coarse silica sand. The ratio of Portland cement to fine sand or fine clay, may be approximately 1.02. The ratio of water-to-binder (Portland cement and SCM) may be approximately 0.55, and the ratio of water-to-powder (binder plus fine clay smaller than 75 microns) can be approximately 0.416. Included with the water and binder/powder mix is an admixture. According to one embodiment, the admixture can include a water reducing admixture, or plasticizer. The fine clay within the aggregate material is unprocessed, and the binder material is approximately 84 to 90 percent cement and 10 to 16 percent SCM. The unprocessed clay, or fine sand, does not undergo any heating, any chemical modification or sifting before being added to the aggregate material.

A dry mineral binder composition includes cement and mineral fillers for the manufacture of molded parts by way of 3D printing. The binder composition additionally contains at least one aluminum sulfate-based accelerator, at least one polycarboxylate ether-based super-plasticizer and at least one rheology additive.

A green body for a 3D ceramic and/or metallic body is produced by providing a metal or a mixture of metals and/or a metalloid and/or a non-metal or mixtures thereof in form of at least one aqueous solutions, such as a metal nitrate solution; if more than one aqueous solutions are provided, they differ in composition and/or isotope concentration. One aqueous metal solution is mixed with a gelation fluid at a first temperature to suppress an internal gelation of the feed solution mixture prior to its ejection. The feed solution mixture is ejected by inkjet printing to the green body under construction. The ejected feed solution is heated mixture on the green body to a second temperature to fix it on the green body under construction. Several process steps are repeated according to a 3D production control model until a desired form of the green body is attained.

The present invention relates to a three-dimensional (3D) printing process for the (layer-by-layer) production of at least one at least three-layer concrete-comprising segment (subregion) of a three-dimensional (3D) object based on concrete. In the process, a first concrete layer is firstly produced by extrusion of fresh concrete. Subsequently, a first adhesive layer is applied on top of the upward-facing side of the first concrete layer, after which a second concrete layer is applied to the upward-facing side of the first adhesive layer. Further adhesive and concrete layers can optionally be applied in succession, with the corresponding concrete layers and adhesive layers in the respective segment being arranged on top of one another in alternating order and the uppermost layer and the lowermost layer of the respective concrete-comprising segment being in each case formed by a concrete layer. The present invention further provides an at least three-layer concrete-comprising segment of a 3D object as such, which is produced by the process of the invention. The invention further provides for the use of at least one at least three-layer concrete-comprising segment as such for producing a 3D object or for incorporation into a 3D object. The present invention further provides a three-dimensional (3D) object as such, comprising at least one at least three-layer concrete-comprising segment which is able to be produced by the process of the invention.

In a method for the 3D-printing of hydrous mineral binder compositions, an aqueous accelerator is mixed with the binder composition in a continuous mixer. The method is very robust and makes it possible to quickly print even large moulded bodies having a uniform aesthetic surface and very good strength development properties.

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.
