Abstract

Composite materials made from reactive compounds such as oxides are disclosed. The materials comprise a reaction producing of metal oxide, phosphate and reactive residual materials. The metal oxide may comprise MgO, CaO, ZnO, TiO2 or the like. The phosphate may comprise mono-potassium phosphate, mono-ammonium phosphate, mono-sodium phosphate or the like. The reactive residual material may be ash, phosphate clay, phosphate residual slurry, mining waste or the like. The composite materials may be used for many applications including rapid repair materials, pre-cast structures, in-situ structures, mixes and coatings.
