The composition applied to the refractory structure has a magnesia-based refractory material, calcia source and a binder. After application of the refractory material to a refractory structure and upon application of heat to the applied refractory material a matrix is formed which protects against penetration of the slag into the refractory material. The resulting refractory material has improved hot strength, slag resistance and durability.

An apparatus for the gunning of a material is provided having a nozzle with an inner passage having an inlet end into which a wetted material is to be introduced and an outlet end from which the material is to be sprayed. An outer passage is disposed around the inner passage and in fluid communication therewith and has an inlet end for introducing a gas to be passed through the outer passage and impinged on the wetted material passing through the inner passage. Also provided is an apparatus for the gunning of a material having a material delivery hose for providing a material. A water inlet in fluid communication with the material delivery hose provides water to wet the material and a nozzle outputs the wetted material. A mixing chamber is disposed intermediate and in fluid communication with the material delivery hose and the nozzle and has at least one inlet for introducing a mixing gas.
