Claim 0:
1. A method for preparing an uncalcined geopolymer-based refractory material, the method comprising the steps of:
(a) mixing a mineral powder, a fly ash, a metakaolin, and silicon carbide whiskers by ball milling to form a milled material;
(b) mixing the milled material with a sodium water glass solution and water to form a slurry; and
(c) curing the slurry to obtain the uncalcined geopolymer-based refractory material,
wherein the uncalcined geopolymer-based refractory material comprises (i) a geopolymer matrix formed by polymerization of a mixture consisting of the mineral powder, the fly ash, and the metakaolin, and (ii) the silicon carbide whiskers embedded in the geopolymer matrix.
