Alkali-Activated Natural Aluminosilicate Materials for Compressed Masonry Products, and Associated Processes and Systems
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.
