The method is accomplished by having a casing affixed about the area of the equipment component or part subject to the abrasive wear. A wear-resistant concrete material is cast into the spacing between the casing and the surface of the equipment. A wear-resistant ceramic plate or steel plate can also be affixed to the surface of the equipment prior to casting the concrete in place.

Method for reinforcing and repairing equipment parts and components

The present invention relates to combined structures of ceramic material and super concrete, which structures comprise an outer layer of ceramic material bonded to an internal structure of super concrete or an outer structure of super concrete bonded to an inner layer of ceramic material. The ceramic material is selected among any class of inorganic non-metallic products which are subjected to a temperature of 540.degree. C. and above during manufacture or use, while the super concrete comprises densely packed particles of inorganic materials embedded in a matrix based on an hydraulic cement and having a strength of at least 70 MPa.
