Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE TRATAMIENTO DE UN MATERIAL PULVERULENTO A BASE DE SULFATO DE CALCIO PARA PREPARAR UN LIGANTE HIDRAULICO. ESTE PROCEDIMIENTO CONSISTE EN COMBINAR DOS ETAPAS DE TRATAMIENTO SUCESIVAS: (A) CALENTAR EL MATERIAL PULVERULENTO EN UN TUNEL DE COCCION (1) A UNA TEMPERATURA COMPRENDIDA ENTRE 220 (GRADOS) C Y 360 (GRADOS) C EN CONDICIONES APROPIADAS PARA FORMAR MAYORITARIAMENTE SULFATO DE CALCIO DE VARIEDAD AL}, (B) SOMETER EL MATERIAL ASI CALENTADO A UN TEMPLE TERMICO EN UN DISPOSITIVO DE ENFRIAMIENTO (2) MEDIANTE UN GAS FRIO Y SECO PARA ESTABILIZAR LA ANHIDRITA AL} Y BLOQUEAR SU EVOLUCION HACIA OTRAS VARIEDADES CRISTALOGAFICAS. EL PROCEDIMIENTO PERMITE OBTENER UN NUEVO LIGANTE HIDRAULICO CON UNA PROPORCION PONDERAL DE ANHIDRITA AL} SUPERIOR AL 35 % QUE TIENE CARACTERISTICAS MEJORADAS DE ESTABILIDAD AL FUEGO Y DE RESISTENCIA.
