Zusammenfassung:AbstractThe increased contribution of science-intensive clean materials and technologies to the total industrial production is one of the essential prerequisites for the future of sustainable industrial development. Chemical activation based on a nonfired or low-temperature approach for the production of cementitious materials from glassy aluminosilicates, including calcined clays, is an intensively developing and promising clean technology. This study investigated the potential of calcined clays as precursors of alkali-activated cements (AACs) by considering three types of low-grade multimineral clays (with a clay mineral content of
