Hexavalent chromium-free slurry formulations which are suitable in the production of ceramic overlay coating systems are described. The formulations provide superior hot corrosion and heat oxidation protection for superalloy substrates. A basecoat slurry and topcoat slurry are provided. The basecoat slurry includes an aluminum phosphate based aqueous solution having a molar ratio of Al:PO.sub.4 higher than about 1:3 with the incorporation of metal oxide particles. The topcoat slurry includes an aluminum phosphate based aqueous solution having a molar ratio of Al:PO.sub.4 higher than about 1:3. Both of the basecoat slurry and the topcoat slurry are hexavalent chromium-free.

A packaged additive for preparing a cementitious composition comprises a water-soluble paper container and at least one non-liquid additive packaged within the water-soluble paper container. A kit for preparing a hardenable cementitious composition comprises the packaged additive and a separate packaged base cementitious material. Also disclosed is a method for preparing a hardenable cementitious composition using the packaged additive and separate base cementitious material components of the kit, and a method for repairing a flaw in a cementitious structure using the hardenable cementitious composition prepared with the packaged additive and the separate base cementitious material.
