Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. The first particulate mix includes greater than 50 weight percent of first metallic particles.

Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. Locations of the first pattern have a first average thickness perpendicular to the slab width and the slab length, and locations of the second pattern have a second average thickness perpendicular to the slab width and the slab length that is different from the first average thickness.

Systems and methods are disclosed for producing a shaped cementitious article comprising mixing foamed glass aggregate particles, Portland cement, and water, placing the mixture into a mold, applying vibration and/or pressure to the mold, removing the mold, and then curing the molded concrete article. The shaped cementitious article may be a concrete block (e.g., a solid block, a hollow block, a flue, a curb, or a paver). The concrete block may be a relatively lightweight formed concrete block defining a hollow interior portion (e.g., “cinder block” shaped).
