A cementitious matrix consisting essentially of aluminosilicate polymer containing a liquid component of an aqueous solution of an alkali metal silicate having the formula M2O.RSiO2.XH2O, in which: M is an alkali metal monovalent cation such K+ or Na+; R is the molar ratio of SiO2/M2O, where the range is between 0.5/1 and 9/1; and X is the amount of water, where the amount of water is between 30 and 70 wt %; and a powder component which contains the silico-aluminous reactive raw materials Al6Si2O13 and Al2O3.4SiO2, with a relative proportion between 40 and 60 wt %, where the particle size of both components ranges between 40 and 70 microns. The cementitious matrix has high mechanical strength and is resistant to high temperatures. |
