Inorganic coatings that may be used to coat and protect concrete are disclosed. The protective inorganic coatings include a liquid composition portion comprising water, an alkali metal oxide component and a silicate-containing component. The coatings also include a powder composition portion comprising microspheres, metal oxide powder and optional microfibers. When applied to concrete, the coatings provide chemical and physical protection.

The present invention relates to a basalt fiber reinforced concrete, which includes: a cement slurry with a water-to-cement ratio between 0.3 and 0.5, and a slurry volume percentage between 15-25%; an aggregate with an aggregate volume percentage between 65% and 75%; a basalt fiber reinforcement with a fiber volume percentage between 0.2% and 1.00%; and a concrete admixture used to adjust the properties of the basalt fiber reinforced concrete.

The invention described is a reinforced refractory fire containment wall panel, the panel cast from a reinforced refractory composition. The refractory composition contains cement, a binder, a matrix material comprising 300 series stainless steel fibers and organic fibers, and a refractory aggregate comprising aluminum oxide, calcium oxide, iron oxide and silicon dioxide or a combination thereof, and a reinforcing material. The invention also describes methods of making the reinforced refractory fire containment wall panel.
