Abstract
An uncalcined geopolymer-based refractory material is provided, comprising a matrix of a geopolymer obtainable by polymerization of a mixture consisting of mineral powder, fly ash, and metakaolin; and SiC whiskers embedded in the geopolymer matrix. The material has excellent mechanical properties and high resistance to high temperatures and exhibits a ductile fracture mechanism instead of a brittle fracture mechanism.
