Abstract

L'invention concerne un perfectionnement aux briques isolantes réfractaires à base de perlite expansée ayant des pores qui sont vitrifiés sur leur peau extérieure, consistant en un squelette de liant et ciment de Portland et des pores essentiellement fermés avec une peau extérieure vitreuse, selon le brevet principal et à leur procedé de production. Dans les briques selon l'invention, des grains d'une roche magmatique contenant un feldspath et/ou une matière feldspathique sont noyés dans le squelette de liant.The invention relates to an improvement in insulating refractory bricks based on expanded perlite having pores which are vitrified on their outer skin, consisting of a skeleton of Portland cement and binder and essentially closed pores with a glassy outer skin, according to the patent. main and their production process. In the bricks according to the invention, grains of a magmatic rock containing a feldspar and / or a feldspathic material are embedded in the binder skeleton.
