Abstract: 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.
