Corrosion-resistant refractory binder compositions may be formed with a calcium ion source, high-alumina refractory aluminosilicate pozzolan, and water. Any one or more of such components may individually be non-cementitious. Examples of high-alumina refractory aluminosilicate pozzolan include crushed firebrick; firebrick grog; and mixtures of silicate and any one or more of corundum, high-alumina ceramic, and bauxite; refractory mortar; fire clay; mullite; fused mullite; and combinations thereof, among others. A binder composition may be mixed with sufficient amount of water to form a slurry, which slurry may be introduced into a subterranean formation (e.g., via a wellbore penetrating the subterranean formation). A plurality of the non-cementitious components may react in the presence of water when exposed to suitable conditions so as to enable the binder composition to set. Such compositions, once set, may exhibit enhanced corrosion and/or heat resistance as compared to other binder compositions. |
