Un cemento de magnesia refractaria que se adhiere hidráulicamente y químicamente, que comprende un componente de magnesia cáustica que tiene un área superficial específica BET de al menos 0,5 m2/g, y un componente de ácido carboxílico, caracterizado por que el componente de ácido carboxílico se compone de al menos un ácido carboxílico que es solo ligeramente soluble en agua y/o tiene una baja tasa de disolución en soluciones acuosas, es decir, tiene una solubilidad a 20 °C de 0,5 a 50 g/l, o una tasa de disolución en una solución acuosa a 20 °C o de 1 a 50 g/l/h.
The invention relates to a hydraulically and chemically bonding refractory cement, which comprises a caustic magnesia component having a BET specific surface area of at least 0.5 m 2 /g, and a carboxylic acid component, wherein the carboxylic acid component consists of at least one carboxylic acid that is only slightly water soluble and/or has a low dissolution rate in aqueous solutions, and which carboxylic acid component is capable of generating at least one soluble magnesium salt upon contact of said cement with water. The invention further relates to a corresponding refractory material containing the magnesia cement and to uses thereof for the manufacture of products useful in various industries.
