Abstract

La invención se refiere a un mortero mejorado que comprende cementos de sulfoaluminato de calcio, áridos silíceos y agua, en donde dichos áridos silíceos se encuentran parcialmente sustituidos por cenizas volantes procedentes de la incineración de residuos sólidos urbanos, inertizadas en forma de carbonatos. Estas cenizas inertizadas tienen un contenido en cloruros inferior al 1% en peso con respecto al peso total las cenizas. También se describen los métodos de fabricación de los mismos y otros materiales de construcción fabricados a partir de mortero.The invention relates to an improved mortar comprising calcium sulfoaluminate cements, siliceous aggregates and water, wherein said siliceous aggregates are partially replaced by fly ash from the incineration of urban solid waste, inerted in the form of carbonates. These inertized ashes have a chloride content of less than 1% by weight with respect to the total weight of the ashes. The manufacturing methods of the same and other construction materials made from mortar are also described.
