Abstract

El campo de aplicación del invento lo constituye la fabricación de yeso mejorado. Los procedimientos conocidos para obtener yesos mejorados son derealización muy costosa y dan productos de propiedades no constantes. Para obtener un nuevolig ante hidraúlico de propiedades definidas y que, una vezendurecido, tenga características sobresalientes de comportamiento frente al fuego y de resistencia mecánica, el invento propone, partiendo de la materiaprima pulverulenta a base desulfato de calcio, (a) calentar dicha materia a 220-360°C en un túnel de cochura, en condiciones adecuadas para que se formemayoritariamente sulfato de calcio alfa (anhidrita alfa); (b) someter el material así calentado a un endurecimientotérmico en un dispositivo deenfriamiento, mediante un gas frío y seco, a fin de estabilizar la anhidrita alfa y bloquear su evolución a otras formas cristalinas. Los liganteshidráulicos obtenidos tienen una proporción ponderal de anhidrita alfasuperior al 35%, un mejor comportamiento frente al fuego y mayor resistencia mecánica.
