Abstract

Se describen materiales reactivos cementicios producidos a partir de materias primas inorgánicas abundantes globalmente. También se describen métodos para la manufactura de tales materiales reactivos cementicios y la formación de los materiales reactivos como partículas vítreas microesferoidales. También se describen aparatos, sistemas y métodos para la producción termoquímica de reactivos cementicios vítreos con morfología esferoidal. Los aparatos, sistemas y métodos utilizan una tecnología de fusión / enfriado rápido sobre la marcha de tal manera que las partículas sólidas se ponen en suspensión, son fundidas en suspensión, y entonces enfriadas rápidamente en suspensión. Los reactivos cementicios pueden ser combinados con cemento Portland y un activador alcalino para formar un cemento mezclado. Los reactivos cementicios se pueden utilizar en hormigón para reducir sustancialmente las emisiones de CO₂ asociadas a la producción de cemento.Reactive cementitious materials produced from globally abundant inorganic raw materials are described. Methods for the manufacture of such cementitious reactive materials and the formation of the reactive materials as microspheroidal glassy particles are also described. Apparatus, systems and methods for the thermochemical production of spheroidal morphology glassy cementitious reagents are also described. The apparatus, systems and methods use a melting/quenching on the fly technology in such a way that solid particles are slurred, melted into slurry, and then quenched into slurry. Cementitious reagents can be combined with Portland cement and an alkaline activator to form a blended cement. Cementitious reagents can be used in concrete to substantially reduce CO₂ emissions associated with cement production.
