Disclosed are masonry product feedstock compositions having natural aluminosilicate minerals, e.g., clay minerals and feldspars, to activate a geopolymer reaction. During the formation and curing of a masonry product, an alkali activator creates structural bonds within a mix of aggregates in the feedstock having a low moisture content (e.g., 5-10% by weight). The feedstock and manufacturing can require less energy, and can result in a lower environmental footprint than conventional masonry products. Associated processes and systems provide improved mixing and/or de-agglomeration of the feedstock, high compression during the formation of masonry products, and optimized curing. Exemplary products can include structural masonry units, veneer facing blocks, pavers, and other pre-cast products. Because the natural aluminosilicate minerals can be found in minimally processed abundant raw earth, the composition is not limited to conventional geopolymer materials that are sourced from industrial byproducts that are limited in geographic availability.

A construction block or suchlike comprises at least one part made of conglomerate material, to which an insert made of filling material is constrained, to define a connection face for connection to another structural element. The connection face has visible a first surface of the insert and at least a connected second surface of the part made of conglomerate material. On the connection face other structural element(s) are combined, along a support plane (R, R1, R2) provided in correspondence with the connection face, to be stably connected by a layer of binder material. The second surface has a seating made longitudinally and lowered with respect to the support plane (R, R1, R2), on which seating the layer of binder material is located. The seating has a determinate depth (D), with respect to the support plane (R, R1, R2) correlated to the predefined thickness of the binder material to be laid.

Machines and system for 3D printing are disclosed. One machine includes a machine frame having a plurality of ground engaging elements to facilitate movement of the machine frame, a telescoping boom pivotably coupled to the machine frame and configured to pivot along at least a horizontal plane, a material line coupled to the boom and configured to convey a material therethrough, a printhead coupled to the boom and in fluid communication with the material line to receive the material and to dispense the material, and a controller configured to receive 3D printing information and to convert the 3D printing information into positional coordinates of the printhead, wherein the controller is to cause movement of the boom to position the printhead based at least on the position coordinates.
