Claim 0:
1. A method for preparing a zeolite-like material having amorphous phases and three-dimensional aluminosilicate network structures, comprising the following steps:
mixing an inorganic solid waste and an alkali activator, and conducting an alkali activating reaction to obtain an activated waste, wherein the alkali activator comprises the following components in percentage by mass: 20% to 35% of potassium hydroxide, 15% to 20% of potassium silicate, and 50% to 60% of water, and the inorganic solid waste have a total mass content of silica and alumina of greater than or equal to 10%;
mixing the activated waste with a binder to obtain a mixture, and precuring the mixture under heating to obtain a precured waste, wherein the binder is selected from the group consisting of an aluminum oxide and an aluminum salt;
mixing the precured waste with a foaming agent, and foaming to obtain a foamed waste; and
forcibly curing the foamed waste to obtain a cured waste, and calcining the cured waste to obtain the zeolite-like material, having amorphous phases and three-dimensional aluminosilicate network structures.
