Abstract

------ COMPOSITION POUR LA FORMATION D’UN GEOPOLYMERE PRESENTANT UNE TENUE THERMIQUE A DES TEMPERATURES ELEVEES La présente invention porte sur une composition pour la formation d’un géopolymère, comportant : une poudre alumino-silicatée ; et une solution aqueuse alcaline d’au moins un silicate de métal alcalin, caractérisée par le fait que le métal alcalin dudit silicate ou desdits silicates est le potassium, et que la composition comporte, exprimés en oxydes, les constituants SiO2, K2O, Al2O3 et CaO, et le cas échéant les constituants BaO et MgO, dans un rapport molaire : (SiO2 + Al2O3) / (CaO + BaO + MgO + K2O + Al2O3) compris entre 1,31 et 3,31, SiO2provenant de (A) ; K2O provenant de (B) ; Al2O3 et CaO provenant de (A) ; etBaO et MgO, s’ils sont présents, provenant de (A).
